Those Were the Days.

A farce based on Arthur Wing Pinero's play 'The Magistrate' in which the son (John Mills) of a stern magistrate (Will Hay) visits a music hall against the wishes of his father. In true farcical style, the magistrate too ends up at the music hall, and before long all the characters are trying not to avoid each other... Mainly notable (a) because of its depiction of the music hall as seen by a generation which knew it intimately (b) because of its use of music hall acts of the time and (c) because it gave Will Hay his first film role.
