Green Day ripped off Chicago's 25 or 6 to 4 , just slowed it down. We'll never know if Cobain actually did nick Boston's riff, he may have mentioned the simiarity to sort of admit what he did without actually copping to it,( who wants to get sued), or it could have been pure coincidence. Again, we'll never know. David Lee Roth did his sword dance just after Jim Dandy used one on the BOA 84 tour. Rick Neilson of Cheap Trick spits onstage to try & look cool, borrowed from Nuge. & throws his guitar way up high to side of the stage, borrowed from Gene Simmons. Nikki Sixx wears the same clothes as Pete Way of UFO, & even plays same bass. Crue may be top of the list for copystuff. Christian Death's debut album was titled Only Theater of Pain, ( 1981), & Motley's Theater of Pain came out in 83. Montrose's motorcycle riff, the spinning drum riser from ElP, & looks from NY Dolls, Kiss etc. Here's a question, which band was 1st to use a spaceship as a stage design? ELO? Parliment? or Boston?
