I just wrote it in a couple of days, during the Sheer Heart Attack sort of batch where I was writing the songs for the album. It wasn't written or conceived as a single at all, it was just one of the songs, my contributions for the album. It so happened that when we sort of recorded it, we thought that it could make a good single, and we gave it a slightly sort of single's approach to it. But, basically, it's an album track. Back home, it was a double-A side, so Flick of the Wrist was the A-Side as well, so we were sort of putting across a sort of a taste of what was to come on the album.
