In 2006, Kane played this material too broadly, overexploiting a natural gift for grotesque physical comedy: his father was a hulking deformed monster, the Guardianistas fey fools, skipping across the stage. In 2007, the chip on his shoulder was still there, but the ideas were better, the portraits more detailed, more refined; he began to find his balance, which is a rare mixture of inspired verbal sparring and effective physical comedy. Third time’s the charm: Gaping Flaws had almost none. It was still all about class, but some magical integration had occurred. I couldn’t help being struck by the sense that what it might take a novelist a lifetime to achieve a bright comedian can resolve in three seasons. (How to present a working-class experience to the middle classes without diluting it. How to stay angry without letting anger distort your work. How to be funny about the most serious things.)

Audiences love death defiers like Kane. It’s what they pay their money for, after all: laughs per minute. They tend to be less fond of those comedians who have themselves tired of the nonstop laughter and pine for a little silence. I want to call it “comedy nausea.” Comedy nausea is the extreme incarnation of what my father felt: not only is joke telling a cheap art; the whole business of stand-up is, in some sense, a shameful cheat. For a comedian of this kind, I imagine it feels like a love affair gone wrong. You start out wanting people to laugh in exactly the places you mean them to laugh, then they always laugh where you want them to laugh-then you start to hate them for it. Sometimes the feeling is temporary. The comedian returns to stand-up and finds new joy in, and respect for, the art of death defying. Sometimes, as with Peter Cook (voted, by his fellow comedians, in a British poll, the greatest comedian of all time), comedy nausea turns terminal, and only the most difficult laugh in the world will satisfy. Toward the end of his life, when his professional comedy output was practically nil, Cook made a series of phone calls to a radio call-in show, using the pseudonym Sven from Swiss Cottage (an area of northwest London), during which he discussed melancholy Norwegian matters in a thick Norwegian accent, some of the funniest and bleakest “work” he ever did.

At the extreme end of this sensibility lies the anticomedian. An anticomedian not only allows death onstage; he invites death up. Andy Kaufman was an anticomedian. So was Lenny Bruce. Tommy Cooper is the great British example. His comedy persona was “inept magician.” He did intentionally bad magic tricks and told surreal jokes that played like Zen koans. He actually died onstage, collapsing from a heart attack during a 1984 live TV broadcast. I was nine, watching it on telly with Harvey. When Cooper fell over, we laughed and laughed, along with the rest of Britain, realizing only when the show cut to the commercial break that he wasn’t kidding.

There was an anticomedian at Edinburgh this year. His name was Edward Aczel. You will not have heard of him-neither had I; neither has practically anyone. This was only his second Edinburgh appearance. Maybe it was the fortuitous meeting of my mournful mood and his morbid material, but I thought his show, Do I Really Have to Communicate with You?, was one of the strangest, and finest, hours of live comedy I’d ever seen. It started with neither a bang nor a whimper. It didn’t really start. We, the audience, sat in nervous silence in a tiny, dark room, and waited. Some fumbling with a cassette recorder was heard, faint music, someone mumbling backstage: “Welcome to the stage… Edward Aczel.” Said without enthusiasm. A man wandered out. Going bald, early forties, schlubby, entirely nondescript. He said, “All right?” in a hopeless sort of way, and then decided that he wanted to do the introduction again. He went offstage and came on again. He did this several times. Despair settled over the room. Finally, he fixed himself in front of the microphone. “I think you’ll all recall,” he muttered, barely audible, “the words of Wittgenstein, the great twentieth-century philosopher, who said, ‘If indeed mankind came to earth for a specific reason, it certainly wasn’t to enjoy ourselves.’ ” A long, almost unbearable pause. “If you could bear that in mind while I’m on, I’d certainly appreciate it.” Then, on a large flip chart, the kind of thing an account manager in an Aylesbury marketing agency might swipe from his office (Aczel is, in real life, an account manager for an Aylesbury marketing agency), he began to write with a Magic Marker. It was a list of what not to expect from his show. He went through it with us. There was to be

No nudity.

No juggling.

No impressions of any well-known people.

No reference to crop circles during the show.

No one will be conceived during the show.

No tackling head-on of any controversial issues…

And finally, and I think most important-

No refunds.

I recognized my father’s spirit in this list: No good can come of this. He then told us that he had a box of jigsaw puzzles backstage, for anyone who became dangerously bored. Later, he drew a graph made up of an x-axis, which stood for “TIME,” and a y-axis, for “GOODWILL,” on which he tracked the show’s progress. Point one, low down: “Let’s all go and get a drink-this is pointless.” Point two, slightly higher up: “O.K., carry on, whatever.” Point three, still only halfway up: “We could all be here forever. We think this is great.” He looked at his shoes, then, with mild aggression, at the audience. “We’ll never get to that point,” he said. “It’s just… it’ll never happen.” By this time, everyone was laughing, but the laughter was a little crazy, disjointed. It’s a reckless thing, for a comedian, to be this honest with an audience. To say, in effect, “Whatever I do, whatever you do, we’re all going to die.” When it finally came to jokes (“Now we go into the section of the show routinely called ‘material,’ for obvious reasons”), Aczel had a dozen written on his hand, and they were very funny, but by now he had already convinced us that jokes were the least of what could be done here. It was an easy and wonderful thing to believe this show a genuine shambles, saved only by our attention and by chance. (We were mistaken, of course. Every stumble, every murmur, is identical, every night.) In the lobby afterward, calendars were on sale, each month illustrated by impossibly banal photographs of Aczel in bed, washing his face, walking into work, standing in the road. Mine sits on my desk, next to my father in his Tupperware sandwich box. On the cover, Aczel is pictured in a supermarket aisle. The subtitle reads, “Life is endless, until you die”-Edith Piaf. Each month has a message for me. November: “Winter is coming-Yes!” April: “Who cares.” June: “This is not the life I was promised.” There is plenty of hope, an infinite amount of hope-but not for us!

On the last night of the Edinburgh festival, in another small, dark, drunken venue, I waited for my brother to go on. It was about two in the morning. Only comedians were left at the festival; the audiences had all gone home. I feared for him, again-but he did his set, and he killed. He was relaxed. There was nothing riding on his performance; the pause had been fixed. Then a young Australian dude came on and spoke a lot about bottle openers, and he killed, too. Maybe everybody kills at two in the morning. Then the end of the end: one last comedian took the bar stage. This was Andy Zaltzman, a great, tall man with an electrified Einstein hairdo and a cutting, political-satirical act that got its laughs per minute. He set to work, confident, funny, and instantly got heckled, a heckle that was followed by a collective audience intake of breath, for the heckler was Daniel Kitson, a rather shy, whimsical young comedian from Yorkshire who looks like a beardy cross between a fisherman and a geography teacher. Kitson won the Perrier Comedy Award in 2002, at the age of twenty-five, and his gift is for the crafting of exquisite narratives, shows shaped like Alice Munro stories, bathetic and beautiful. A comedy-snob thrill passed through the room. It was a bit like Nick Drake turning up at a James Taylor gig. Kitson good-humoredly heckled Zaltzman, and Zaltzman heckled back. Their ideas went spiraling down nonsensical paths, collided, did battle and separated. Kitson busied himself handing out fliers for “Our joint show, tomorrow!”-a show that couldn’t exist, because the festival was over. We all took one. Zaltzman and Kitson got loose; the jokes were everywhere, with everyone, the whole room becoming comedy. There was a kind of hysteria abroad. I looked over at my brother and could see that he’d got this abdominal pain, too, and we were both doubled over, crying, and I wished Harvey were there, and at the same moment I felt something come free in me.
