We often see youTube clips and say "why don't they put great music on TV anymore?". I agree that there aren't nearly as much classical and jazz on TV. But there is great music on TV.
I remember in the early 90's the David Sanborn show on NBC. That was awesome. Also the Jools Holland show on BBC is really good. Jools was actually in the Sanborn show band and had a legendary confrontation with Dizzy.
I love the Daryl Hall show.
