Led Zepplin came after the band Iron Butterfly, which is practically the same thing. (Iron Butterfly played at Rec Hall, by the way).
The Peanut Butter Conspiracy was a great band name but lousy music, which included the immortal lyrics "Love is the grooviest thing that there is in the world up 'till now." (from the song "It's a Happening Thing.")
Think that name doesn't belong here? Well, quite seriously, I have remembered the group moniker just as easily as Led Zeppelin since the very first time I heard it. Now, who is the better band probably depends on your age and music preference at the time you make such a call.
I just had a vision of a group of old women on one of the double decker tour buses rolling down South Street and they look up at the marquee of the TLA and see Butthole Surfers on the same bill as Pussy Riot and The Bare Naked Ladies.
Led Zeppelin, Grateful Dead, Rolling Stones, Buffalo Springfield, Mott The Hoople ( Fking love Mott the Hoople ) Jefferson Airplane, Big Brother and the Holding Company, that era had a lot of cool names.
Hell, the Beatles is a cool name.
Currently it seems to favor animals, Deer Tick, Grizzly Bear, etc. etc.
