I don't think it can have had an X certificate - my school film club showed it. (That same weekend, ITV showed _The Collection_ - a new Harold Pinter play with Malcolm McDowell, Alan Bates and Laurence Olivier. What a weekend that was.)

FB - Alan Price and his then band (not sure if it's the Set) are a recurring presence throughout the film; they play all the music, most of it on camera, and at one crucial juncture give the main character a lift to London.

Arthur Lowe, Mona Washbourne, Rachel Roberts, Ralph Richardson, Helen Mirren, Peter Jeffreys ("You have eyes like Steve McQueen"), I could go on. And a wonderful, wonderful central performance by Malcolm McDowell in his young and beautiful frog-faced prime*. My favourite film of all time.

*He was, I maintain, quite astonishingly beautiful when young, but it's hard to deny that he looked like a frog. See also Tilda Swinton.
