This hasn't aged well. A young Murphy, recorded with a large audience, may have been cutting edge in 1983 but it all looks very dated now. His delivery - impressions, movement, enthusiasm and physicality - are brilliant and formed the basis of his successful acting career, however bland the films sometimes were. But his material is crude, obvious and rarely funny: the sort of stuff about farting and homosexuals that kids in a school playground like due to its initial novelty and rudeness; most grown-ups have heard it all before and moved on. Despite this, the audience are wetting themselves at his every move.
It's a sad reflection that the biggest laugh of the act is provided by an audience member. Richard Pryor must have turned in his grave at this pale imitation of his groundbreaking style.
