Checking out a PBS presentation of Ron Howard's Beatles movie & the press were asking them about their hair. I thought that was odd, because their hair was no longer than mine was as a pre-teen. Heck, I think Paul's hair might actually be longer now than it was then. Anyway, it started me thinking about when & who started the long-hair revolution that seemed to cling to Rock & Roll. Deep Purple, Led Zeppelin, Black Sabbath (all kind of late to the hair party) MC5, Alice Cooper, Steppenwolf Who was it?
