"Smashing Time is a 1967 British comedy film starring Rita Tushingham and Lynn Redgrave. It is a satire on the 1960s mediainfluenced phenomenon of Swinging London.
It was written by George Melly and directed by Desmond Davis. The supporting cast included Ian Carmichael, Michael York, Jeremy Lloyd, Anna Quayle, Irene Handl, Arthur Mullard and Geoffrey Hughes.

Some of the characters' names are borrowed from Lewis Carroll's poetry, chiefly the nonsense poem Jabberwocky: Charlotte Brillig, Tom Wabe, Mrs Gimble, Bobby MomeRath, Jeremy Tove, and The Snarks (the rock band played by Tomorrow). Additionally the futuristic art exhibition is held at the Jabberwock Gallery.

Private Eye magazine referred to the Queen and Princess Margaret as Brenda and Yvonne (respectively). The film also implies that the Queen is a fan of Yvonne's single."
