I got to listen to the programme last night. Absolutely superb. One of the best music docs I've heard in a long time. The programme moved effortlessly from a general discussion of the blues, to a discussion on Honeyboy, to hoboing in the 30s, to hoboing in the present day, before returning for a round up on Honeyboy. In between it featured interviews with Guy Davis, amongst other, and reminiscences of Honeyboy being recorded by Alan Lomax for the Library of Congress.

And all this against an continuous soundtrack of music by Son House, Robert Johnson, Tommy Johnson, Charely Patton, Howlin' Wolf, Big Joe Williams and a great many other blues singers whom he mixed with.

If you haven't caught it yet, it will be on Iplayer until Tuesday night.
