on 19 August, immediately before the final mix. Though not released as a single, the song attracted attention and critical praise, and was included on the compilation 1967–1970. It has been featured several times on BBC Radio 4's Desert Island Discs, having been chosen by Sandie Shaw, Jerry Springer, Boris Johnson and Elaine Paige. The Daily Telegraph's Martin Chilton said it was "almost impossible not to sing along to".
