Sir Henry Irving's works. During the 1930s it was used to premiere several works by
Ian Hay before they transferred to the
West End including
Orders Are Orders and
Admirals All. The musical ''
This'll Make You Whistle'' premiered there in 1935. The theatre stayed in the control of its original owners, The Portsmouth Theatre Company, until 1964 when it was purchased by Commander Reggie & Mrs Joan Cooper. ==The Kings Theatre Trust Ltd==
