There was a reason Cleveland got the Rock N Roll Hall Of Fame. They supported a lot of smaller or second tier rock acts with commercial airplay including Zappa, Roxy Music, Mott The Hoople, Rare Earth, Hawkwind etc.
They also gave considerable airplay to King Crimson, Weather Report (Bird Land) Stanley Clarke's School days & All of Jeff Beck's fusion stuff. That was probably the only good thing about Cleveland back then.
At Midnight they had a show called import hour where they played bands like NEU!, The Pink Fairies etc.
