One thing you might want to remember about classic rock, the fans that made songs like that popular, grew up listening to AM radio and 45's on the turntable, until album oriented rock started happening the radio only played 2:59 min. stuff, and we live in a world that celebrates "Firsts", Who was the first guy to climb Mt.Everst, OK, who was the last? Milestones of the past look smaller in the rearveiw mirror, alot of people may do something better latter, but they have to walk in other's footsteps to do it, Even though I think I have heard Stairway to Heaven enough times, it does amaze me that even after all these years, people that have heard it a million times and people that are hearing it for the first time still get off on it, their must be something there....
