Song of Summer is a 1968 black-and-white television film co-written, produced, and directed by Ken Russell for the BBC's Omnibus series which was first broadcast on 15 September 1968. It portrays the final six years of Frederick Delius' life, during which Eric Fenby lived with the composer and his wife Jelka as Delius's amanuensis. The title is borrowed from the Delius tone poem A Song of Summer, which is heard along with other Delius works on the film's soundtrack.
