Camoletti was born a French citizen in Geneva, Switzerland, though his family had Italian origins.

His grandfather was the architect who designed the concert venue Victoria Hall in Geneva, the Musée d'art et d'histoire and the Hôtel des postes du Mont-Blanc.

The original 1962 London production, in an adaptation by Beverley Cross, opened at the Apollo Theatre, transferred to the Duchess, and ran for seven years, racking up more than 2,000 performances.

A later play, Don't Dress for Dinner, also ran for seven years in London, again transferring from the Apollo to the Duchess.
