The story of acerbic 1960s comic Lenny Bruce, whose groundbreaking, no-holds-barred style and social commentary was often deemed by the Establisment as too obscene for the public.

In 2007, Stewart Lee was voted the 41st best stand-up of all time in an official Channel 4 poll, apparently better than Lenny Bruce but not as good as Jim Davidson. But what real difference does this accolade make? His TV pilot has been cancelled and his mother still thinks the 1970s game show host Tom O’Connor is funnier than him.

Billy Connolly was, in the 1970s, a sort of Scottish Lenny Bruce, who, with devastating humour, sliced through the hypocrisies he perceived. This 1976 documentary follows the singer-comic during his 1975 Irish tour. Made in a cinema verité fashion, the performer appears to be completely unaware of the presence of the camera in his off-stage and backstage moments.
