First assembled as White Clover in 1970, the Topeka, Kansas, ensemble kicked around for a few years before solidifying a lineup and changing its name to one that matched the members' license plates. Eventually, music mogul Don Kirshner became interested in the group's not-very-radio-friendly mix of progressive rock and rural emotion. Four decades of basically the same lineup and sales of 30 million records followed. The band's hits "Carry On Wayward Son," "Dust in the Wind" and "Point of Know Return" continue to be staples of classic rock airplay.

"One of the most memorable ones we played was up in Wisconsin called Nudestock. It was a nudist colony. Foreigner was on the bill and Alan Parsons. But you expect up in Wisconsin there'd be all these beautiful blond women. But the reality is never what you imagine. You get there and it looks like you walked into a Piggly Wiggly grocery store and suddenly everybody was naked. And you're standing there playing and there's some guy with a baseball hat and tennis shoes standing in front of you, wiggling and playing air guitar with his pecker swirling around. It bothers you."
