... and I don’t remember good. It was “The Roosters” that Clapton started out with, but I seem to recall Carl Palmer did a stint with Atomic Rooster before he hit it big with The Crazy World of Authur Brown. Old age ain’t pretty but it’s all I got.
Carl Palmer did play with The Atomic Rooster
I just checked Wiki and it says Palmer left Authur Brown to become a founding member of Atomic Rooster and jumped from there to ELP. I never even heard of AR until the 80s but I saw TCWoAB with Carl in 1968. That guy was as nutty as Screaming Lord Sutch (who employed Jeff Beck before he was a Yardbird).
