I think I heard the same show (NPR Talk of the Nation), and was disappointed that they didn't play more of his stuff. The thing is... I had never heard of him, and didn't recognize a one of his songs or titles. (Yeah, I need to get a new rock to live under.)
Then again, I'm more a child of the '70s than the '60s. I'm also a bit confused when they call him a rock and roll star. A pop star, okay, but the stuff I heard wasn't really rock and roll to my ears. Too many strings!
