regarding the tom jones thing, the series is on several discs.

One of these discs is "Martin Scorsese Presents The Blues: Red, White and Blues"

this one features Van Morrison, Eric Clapton and Tom Jones discussing british blues.

However, the one that is on BBc4 tonight is a different episode, it is "Martin Scorsese Presents The Blues: Feel Like Going Home" which explores Delta Blues and will feature Willie King and Muddy Waters, etc. i think there will be or is a box set with each episode on. Maybe BBC4 will show the others another time.

Anyway its on in 3 minutes, see ya later, lol.

you can type scorsese blues in amazon and check out the DVD results for all of them.
