Frederick Delius is a classical composer who lived and worked ca. 50 years ago. There's also a film about him and Eric Fenby ("in B, Fenby!") who worked for Delius by writing down the compositions for him (Delius was paralysed and couldn't do that by himself anymore). The film is called "Song Of Summer" (1968) and was directed by Ken Russell. Excerpts from the film are shown during an interview of Eric Fenby, Kate Bush and Julian Lloyd-Webber on the Russel Harty Show. During that show the video to the song Delius was shown for the second time (the Dr. Hook special being the first time).
The Infant Kiss:
The song is inspired by the movie "The Innocents", starring Deborah Kerr, which is based on Henry James' book "Turn of the Screw".
