You guys bring up a good point concerning some of the hard rock bands and even some of the hair bands (at least you now have some novelty shows like Dee Snider's House of Hair etc). Rainbow, UFO, etc don't get hardly any radio play at all and I don't know if I have ever heard a station play Saxon unless it was on a novelty show.
Let me throw in Zebra-Who's Behind the Door
Here is what I don't get. It's a good song but I hear Autograph's "Turn Up the Radio" all the time on classic rock radio. That was their only hit and unless you are a fan of 80's hard rock like some of us are, the average rock fan (Even a lot of classic rock fans) could not even tell you who Autograph were or what album that song came off of (Sign In Please). How does that one sneak in a regular playlist but using Paul's choice not Axe "Rock N Roll Party in the Streets."
While we are at it, outside of a few songs, the Nuge doesn't get a lot of play on classic rock radio, and I have always been surprised rock legend Alice Cooper doesn't either outside of stuff like School's Out or Eighteen. Alice is still around, putting out some pretty good albums, and people forget how big he was at one point. He has 14 Top 40 hits. Why do you never hear something like "Under My Wheels" or "I Never Cry"
