From the wiki: “‘Last Dance’ was written by Paul Jabara and was first recorded by him in 1978. According to the song’s co-producer Bob Esty, Paul Jabara locked Donna Summer in a Puerto Rico hotel bathroom and forced her to listen to a cassette of him singing a rough version of ‘Last Dance’. Summer liked the song and Jabara asked Esty and her producer Giorgio Moroder to work with him on an arrangement for Summer to use for her recording.
