Julian Penkivil Slade (28 May 1930 – 17 June 2006) was an English writer of musical theatre, best known for the show Salad Days, which he wrote in six weeks in 1954,[1] and which became the UK's longest-running show of the 1950s, with over 2,288 performances.
During his time at the Old Vic, Slade wrote incidental music for several productions including Two Gentlemen of Verona and The Duenna.[2] In 1954 ,he was asked to write a musical for the Old Vic Summer Season. It was then that he came up with Salad Days with Dorothy Reynolds.[2] The show was such a success that it moved to London, where it ran for over 2,288 performances[5] - a record at the time. It was in London that a young Cameron Mackintosh saw the show with his aunt and decided to become a theatrical producer. Slade and Mackintosh stayed close friends throughout his life.
Slade's second most successful musical was Free as Air, written with Dorothy Reynolds, which opened at the Opera House in Manchester in 1957, before moving to the Savoy Theatre, London, where it ran for 417 performances.[2]
