Hitman's finished version had very little to do with the original idea. Most of the riff came from Freddie. I wasn't even in the room when they wrote it. I changed the key and some of the notes to make it playable on the guitar. We finished the backing track, but it seemed to ramble. John sat down and decided to reconstruct the track. He changed the order. He changed everything. I went back and played on that. Then we filled in the gaps on the lyrics, did the harmonies and generally tidied up.
