well, the thing about all THREE groups are the MAJOR singers: Alex Chilton Pete Ham Eric Carmen (not mention the other guys: Chris Bell, Jody Stephens, Dave Smalley, Wally Bryson, Joey Molland, Tom Evans).... in each case, the band has a singer of MONUMENTAL importance.... Alex Chilton's vocals on the Big Star albums (especially "Radio City") is unmatched... but very personal... Pete Ham's voice is one of the all-time most beautiful creations... and of course Eric's which even goes a step further and delivers this Steve Marriott-esque punch that neither of those 2 could muster...
