Goodwin wrote several Disney film scores during the 1970s, including the one used for "One of Our Dinosaurs Is Missing" (1975). He also composed the music and lyrics for a series of animated films. These included "The Selfish Giant" (1971), "The Happy Prince" (1974), and "The Little Mermaid" (also 1974). Goodwin's last film score was for the Danish-made animation film "Valhalla" in 1986. He composed the Yorkshire Television start up music used from their launch in July 1968 to the early 1980s, before ITV had breakfast television.
