riders on the Storm is correct!
and - re floaters, don't you just hate it when you pop into a loo - particularly a public one, with a Q waiting after you - and there is one there left by someone else? Especially if you decide to use the facility, flush - - and the alien floater is still there (and there is still a Q outside----) aaarrrggghhh!!!
(Way back when Billy Connolly did a piece on this, was it on the Crucifixion album?)
