After the first album only Mick Abrahams got the boot, they replaced him with Tony Iommi for a short period before Martin Barre joined. That lineup stayed for Stand Up and Beneft when John Evans joined on keyboards. At this point Glenn Cornick was fired and replaced with Jeffrey Hammond. After Aqualung drummer Clive Bunker actually quit because in his own words he was getting married and the touring lifestyle would no longer work for him. Barrymore Barlow took over on drums and the lineup stayed the same through Thick as a Brick, A Passion Play, and Minstrel in the Gallery when Jeffrey Hammond quit to go back into art.This is when they recruited John Glascock for the Too Old to Rock and Roll … Too Young to Die album. They then made David (Dee) Palmer a full-time member on synthesizer and pipe organ, which stayed that way through Song From the Wood, Heavy Horses, and Stormwatch. After John Glascock’s passing he was replaced by David Pegg, but Barrymore Barlow, John Evans, and Palmer were let go. I believe that Barrymore Barlow actually was quitting anyway at this point. That’s more or less the group through the late ‘60s to the big breakup in 1980.
