This great song was one of Queen's best, and yes, I knew it waaaaay before it was featured in "Shawn Of The Dead". I was actually at Summer Camp (at Camp Langston in Mt Pleasant, TX!) when I heard Queen's "Jazz" album, I think summer of 1979, and this song was on it. I thought it was awesome. Many years later, after Karaoke had started, Queen actually released a CD of their original tracks for karaoke, and this was one of them. I only performed it live once, and this was that time. I'd love to have made it a regular song. I had a little liquid energy encouragement this night ;-) Great tune.
