Charles Murray Winstanley Shadwell (26 March 1898 – 28 July 1979)[1] was a British conductor and bandleader.

Born in Dormans Park, Surrey, he saw military service in the Prince of Wales's Own (West Yorkshire) Regiment before studying at the Royal Academy of Music.

He started his professional career playing piano to accompany silent films, before working as a musical director at theatres in Portsmouth, Brighton, and Coventry.

As well as programmes such as Music Hall, which featured his music and ended with his theme tune, "Down with the Curtain", his own composition, he actively participated in the tradition, started in Britain by variety stars Bebe Daniels and Ben Lyon, of banter between the comedians and their shows' bandleader.

[3] Shadwell also came up with the idea for the wartime radio variety series Garrison Theatre, based on his experiences as an entertainments officer in the First World War.
