Roger Taylor loved the song, and demanded it to be the B-side to Freddie Mercury's "Bohemian Rhapsody
" single - so much so that he apparently locked himself in a cupboard until Mercury agreed. Perhaps there was a good reason Taylor really wanted it to be the "Rhapsody" B-side - the song credit went completely to him, and when the single became a huge smash hit, he received almost equal royalties as Mercury did for "Rhapsody."
This naturally rather annoyed the rest of the band! Songwriting credits and friction over royalties are a common reason why most bands break up. For this reason, Queen later in their career decided to give a collective co-writing credit for all songs, regardless of who contributed. This meant everyone got equal royalties for any singles/hits, which meant there was less friction with members more willing to let their songs/ideas be worked on - knowing they wouldn't lose any credit or royalty money in the process.
