Imitations of the WWRY beat were often used in other songs (covers, mash-ups, re-mixes), advertisements, etc.
One of the best (non) cover-songs with the same beat is, in my opinion, 1993's Lenny And Terence by Carter The Unstopable Sex Machine. http://www.youtube.com/watch?v=TOZitD7T0Sc
Long ago I read somewhere that Brian/Queen doesn't own any rights for this beat, because it already existed before he composed WWRY.
My question is: Does any of you know a song, from before 1977
, with the same stomp-stomp-clap beat? A song that could have inspired Brian?
