re: Would a different lead singer make these groups songs even better.

For the most part I agree that a different sounding voice helps a band, but I gotta say that I can't stand Geddy Lee from Rush. Anytime I hear them I immediately change the station.

Also, it usually worked out pretty well, but to be honest Jimi Hendrix is not much of a singer, maybe the Jimi Hendrix Experience would have been even better with someone more talented as a singer.
