@edgarblythe,
Jools Holland is a national institution. He started out as z keyboard player for Squeeze, then he presented cutting edge music show The Tube.
Later on he got a regular programme called Later with Jools Holland where he invited an electic bunch of musicians to perform.
That's it, the musicians are from all different genres, but they are all good, and there will always be something I like.
On New Year's Eve he has a Hootenanny which is an extended version of Later, but with more musicians and a host of celebrity guests.
