The Happiest Days of Your Life (play)

The Happiest Days of Your Life is a farce by the English playwright John Dighton. It depicts the complications that ensue when because of a bureaucratic error a girls' school is made to share premises with a boys' school. The title of the play echoes the old saying that schooldays are "the happiest days of our lives".

The play was first seen on BBC Television in 1947, and then, after a one-night try-out in the West End later that year, it opened at the Apollo Theatre in March 1948, running for more than 600 performances. It has subsequently been revived, and adapted for broadcasting and the cinema.
