Sam’s Classic Rock Radio?

What has happened to the classic rock radio that we used to know? You know what i'm talking about bands like Cream, Grand Funk Railroad, Pat Travers, Blackfoot, Molly Hatchet, the list goes on and on. When I was young Blondie, Billy Joel and Elton John were not considered classic rock. But nowadays they are well to the people that own the airwaves anyway. Well here are some tunes that you don't hear anymore but this is what classic rock used to be.
