When the great actor-turned-director Michael Blakemore died in December last year, aged 95, his obituarist on the BBC reminded listeners that, as well as being the collaborator of choice for the play wrights Michael Frayn and Peter Nichols, the guiding hand behind A Day in the Death of Joe Egg and Noises Off, a double Tony-award winner for Kiss Me Kate and Copenhagen, the almost-head of the National and the actual and much-fêted head of both Glasgow Citizens and the Lyric Hammersmith, he was a gifted and iconoclastic author. Personally, the commentator said, his favourite book about theatre was Blakemore’s Stage Blood (2013), a coruscating, vengeful memoir of the author’s five years as an associate director at the then nascent National Theatre.
