To his credit, Baddiel was able to turn his mother's presence into a sharp gag against himself. "Can you believe I did all that stuff about porn?" he asked with some incredulity. The same aura of self-deprecating warmth permeated the evening.
This will have surprised many because, to put it politely, Baddiel has not always attracted favourable notices. Over the years, knife-wielding critics have queued up to stab him; he himself admitted that "I'm the Bad Review King". Near the top of the show, he got his self-justification in first: "If you're a working-class comedian and you talk about sex, you're called 'earthy' and 'Rabelesian'. If you're middle-class, it's 'schoolboy' and 'undergraduate'."
A lot of the criticism has focused on Baddiel's laddishness; an audience- member on Sunday shouted out, "Are you king of the lads?" Certainly, he ran through many routines far too blue for publication in a family newspaper and peppered the act with more expletives than a Graham Taylor documentary. The plaster angels that adorn the elegant interior of the theatre seemed to be covering their ears in shame.
Baddiel's now-familiar fascination with porn emerged loud and proud. He even launched into a philosophical rebuttal of Howard Jacobson's contention that men are unable to laugh at porn - "If we thought pornography was true to life, all men would be plumbers".
On occasions - with jokes about Fred West and Nazis, for instance - he crossed that invisible border patrolled by the taste police and wondered sheepishly, "Have I gone too far?" But he only went too far because he's prepared to bare more of himself than other comedians. "What this is about is honesty; that's what I'm obsessed with," he explained at one point. "I'm unembarrassable. I have a real problem not telling people things about myself." Living up to the title of the tour - "Too Much Information" - he made revelations about his personal habits that even guests on Oprah might have shied away from.
The audience - compromising more women than men and apparently containing only one bloke in a replica football shirt - obviously weren't hung up on how to label Baddiel. New Lad? New Confessional? New Labour? Who cares? They were too busy roaring with laughter.
