The toilet-cleaner alter egos of comedy duo Peter Cook (Clive) and Dudley Moore (Derek) bring new meaning to the idea of potty-mouthed humour, taking it to X-rated and deeply politically incorrect extremes. Consisting of head-spinning, alcohol-fuelled studio improvisations supplemented with live tracks (like the cringe-inducing "Bo Duddley"), the first and best Derek and Clive album also serves as brutal social commentary on working-class England as perceived by two of its finest, if thoroughly deranged, satirical minds. Brilliant, dangerous and disturbing.
