Crowds having fun at Mitcham Fair.
Full title reads: "A LONDON SIDESHOW - Mitcham's famous Fair opened once again with historic key."
A man in crowd lifts a huge key over his head and starts speaking - Fair tents in background. He starts speaking: "It is my great pleasure as..." - the speech is cut here and he lifts the key in the air. Presumably he opens the Fair. Crowds cheer. Various shots of the fair - crowds, tents, various rides.
Natural sound only.
