Donna Summer originally wrote this song for Rod Stewart, before changing her mind at the last minute and recording it for her Bad Girls album. Released as a single, it peaked at #2 on the US Billboard Hot 100, her sixth consecutive top five hit in a row.
Summer has the sole writing credit on this track. It was her only hit single that she wrote alone, with no co-writers.
Manning the production desk was Summer's longtime collaborators Giorgio Moroder and Pete Bellotte. The European producers' made-in-Munich dance beat for Summer during the Disco era brought her a string of hits and was also highly influential in the development of Electronica and Techno music.
The best we can tell, this song contains the longest-held note by any female vocalist to make both the US and UK Top 40 at 16 seconds. The overall longest-held one is the 18 second sustained note sung by Bill Withers on "Lovely Day."
