Did Okies get freaked out over John Denver's “Rocky Mountain High” too? LOL. Come on people, have you ever seen a Pentecostal church service in full swing? Tell me THOSE folks aren't altering their brain waves. There are all sorts of ways to “get high”. Sex does it. Led Zep at high volume does it. Lying in the snow looking at the Northern lights does it. Too much Tetris does it. Funny what people latch onto to get upset over, isn't it?
