Freddie’s three-chord rockabilly trick, “Man On The Prowl”, with its zippy Fender Stratocaster riffs and licks – of great appeal to those who’d enjoyed the Presley-esque “Crazy Little Thing Called Love”. A projected single, it was withdrawn in favour of “Thank God It’s Christmas”. “Machines (Back To Humans)” has a very Bowie in Berlin ring about it, partly because producer Mack adds the Fairlight Sampler and bounces Mercury’s vocal against a counter harmony and Taylor’s voice, which is put through the Vocoder.
