I tuned in last night to see what was on. A rake of Bob Dylan documentaries. One about tryna track down his performance on a BBC televised play called The Madhouse of Castle Street, the other one I saw was about Woody Guthrie, Rubin Carter and Lenny Bruce. They were really interesting. It seems they went on really late but I had to go to bed. I think they were mainly old eps of Arena but It was great viewing. I've seen other wonderful stuff on it. I'll reiterate, BBC 4 is great.
