Les Dudek,Pure Prairie League........good ones! Quartermass---long time.How about Quarterflash?
Or....Thin Lizzy? I mentioned this one before,but does anyone remember a band called Flash? They were formed by the original Yes guitarist,Peter Banks.Basically,they were a keyboardless Yes (keys,bass...Rickenbacker,of course.drums.guitar and vocals),although Tony Kaye (original Yes KB player) would play on some songs.I had 3 of their albums.
