I didn't include any world music because I thought the lack of any interest in my RIP Charlie Gillett thread was indicative of the lack of interest in world music generally.
Also worth listening to Late Junction when Verity Sharpe is doing it.
This one has some pretty great stuff on it.
Not sure about the Brel programme but worth a go and I haven't listened to the Ornette Coleman one yet. Dull because of the music or the way it's presented. I could easily live without it to be honest.
I trawl through iPlayer every now and then. I've just worked my way through the music category so far.
