This is one of only two songs written by Mel Brooks for his 1968 film The Producers; the other is "Springtime For Hitler." Much later he would compose the entire score for the remake and stage musical.
"We're Prisoners Of Love" sees crooked producer Max Bialystock a prisoner of Uncle Sam. In the 2005 version, this song is called simply "We're Prisoners Of Love". The title is also that of a musical written in Sing Sing prison after Max is convicted of a financial scam - the theme of the film. Happily though, on account of writing this musical he is pardoned.
