This was the theme song to the movie Ghostbusters II
. Brown was hot at the time, with a #1 single "My Prerogative
," so he was courted to do the song. He was invited to the movie set where he met the cast and the crew. The film's joint music supervisor, Kathy Nelson, suggested he record this song for the movie.
Brown agreed in a deal that involved a small part in the film - he played a doorman who greets the Ghostbusters when they arrive at Gracie Mansion. "You guys got another one of those proton packs? My kid brother really wants one," he asks. "The proton pack is not a toy," Egon (Harold Ramis) tells him. "On Our Own" plays under this scene.
