Credited as the inventors of modern British satire, 'Not Only But Always' charts the searing highs and lows of Peter Cook and Dudley Moore, two very different comedians whose careers and private lives often swung in as uncontrolled and anarchic turns as their wit. From their first meeting as Cambridge undergraduates in 1960, through to Cook's death in 1995 this is an impressively written and performed dramatisation of these two tortured geniuses.
