HH There's dark comedy and then there's Frankie Boyle. The ironically self-proclaimed "Voice of Black America" is actually a pale Scottish man in thick rimmed glasses and a shiny suit, a look which - if you hadn't heard any of Boyle's raw, uncompromising satire before - wouldn't have prepared you for some of the unsettling gags which peppered this 90-minute set.
Often met with sharp collective intakes of breath from the audience, Boyle's routines were reminiscent of the kind of biting punchlines he weaves throughout his appearances on television panel shows such as Mock the Week, Have I Got News For You and 8 Out of 10 Cats.
Assembled into a full show, though, some of his material couldn't quite maintain the momentum generated.
Rarely one to opt for the easy gag, Boyle's set - featuring sideswipes at Gordon Brown, terrorism, and his home country - strangely felt too obvious.
A selection of jokes about Olympic apathy surrounding London's preparations for the 2012 Games fared better, and it was his politicised humour which received the warmest applause.
Perhaps satirising the way audiences respond to 'uncomfortable' material, there was nevertheless a feeling that this set was really an exercise in testing the barriers of taste; seeing just how far he could go.
Despite the room being filled with darkness, you could almost see the collective response - eyes widening in terror, knuckles whitening.
Consequently, lines about religion, paedophilia and Princess Diana were met with a reception that could best be described as "frosty"; at worst, arctic. That he managed to pull himself back from the brink and win back the audience is testament to his comic timing and his infectious personality, grinning like a mischievous boy in trouble.
Although a slight disappointment, this was still a fascinating glimpse of a man with a devilishly dark comic heart.
