Hi, I have one of those lost memories which I am trying to find, it's a classic hand drawn cartoon set in space I think and all I remember is a planet (like Saturn) which was played like a piano (the keys being the rings of the planet).
I gather there was some kind of dispute between the notes, some kind of war, but I mostly recall the planet being a piano.
Does anybody remember this? I though it was a Felix cartoon originally, but I've not had any luck there.
