featured David Bowie on backing vocals and a few lines of spoken word to a rhythm during the middle eight. According to Mercury in a 1982 TV interview, Bowie was unhappy with the results and requested that his vocals be removed days before its parent album was slated to be released.

Alex Petridis of The Guardian gave the album two stars and said: "Like Queen, disco was melodramatic, unrepentantly camp, extravagantly arranged and omnivorous in its influences. Or at
