Not as good as that guy Jethro Tull though. You have interviews with two of the creative minds behind two other seminal English rock acts all of whom broke out at about the same time. I think it's natural that there would be some jealousy and competition between them especially since their styles are vastly different. It might have been easier to pass it off as no more than that but that's not typical of the way musicians do things ala the guitarist in the crowd watching another pull off a hot solo and claiming he could play it better or faster or with more originality. Like it or not there is always some degree of competition between musicians and the higher up the food chain you get the more intense the competition gets.
