I sneaked off to a Mott the Hoople concert in the early seventies and Queen was the opening act (pre-Bohemian Rhapsody). We kept calling them back out for encore after encore. I've been a fan ever since.
They had a LOT of good stuff that didn't get airplay. There's a song called "Sail On Sweet Sister" that I just love. I'll try to get it up and post it later!!
