The Bee Gees had been effectively typecast as a disco group after "Saturday Night Fever", and in a 1978 interview Barry remarked "People think we're just about disco now. Of course that's not true. If you look at the "SNF" soundtrack, there's some dance music, but we also have ballads like 'More Than a Woman'." In an attempt to counter this typecasting, the first single from "Spirits Having Flown" was the ballad "Too Much Heaven". The horn section from Chicago (James Pankow, Walt Parazaider and Lee Loughnane) made a guest appearance on this album. At the time, they were next door working on the Chicago album "Hot Streets". Thus the Bee Gees would return the favour as they appeared on Chicago's song "Little Miss Lovin'" and their keyboardist Blue Weaver appeared on "No Tell Lover". The Bee Gees also recorded "Desire" for the album but it was rejected and instead released as a solo single by their brother Andy.
