The Who rocker Roger Daltrey is shocked the Beatles didn't "go mad" at the height of their fame in the 1960s. The star concedes although his band's level of fame never matched that of the infamous four-piece, he sympathises with the incessant attention bestowed upon the group. He says, "I can't imagine what their life must have been like. It must have been a nightmare. "I can see why people go completely mad in this business. They couldn't go out. We had a few years of screaming girls, but that was it."
