Lyric discussion by Muzzy 

Their producer or manager or somebody wanted them to jump on the disco band-wagon, probably to sell more records. They made this song as sort of a joke.

Looking at the sales of Darsk Side Of The Moon, Wish You Were Here, and The Wall. I don't think they needed to change their music one bit to sell records. Probably the best selling band of all time, at least in the top 5.
