Blues Britannia: (21.00 to 22.30 yesterday) followed last week's BBC4 TV's Heavy Metal Britannia documentary, and was 90 minutes of excellent viewing. It traced how the blues records came into England and were picked up by the likes of Brian Jones, Keith Richards, Mick Fleetwood, Paul Jones, the the band's they spawned copying the music - The Yardbirds, Fleetwood Mac, The Stones etc. A fair amount of time was given over to interviewing the black blues artistes; Champion Jack Dupree, Muddy Waters, John Lee Hooker etc; so it was another tiny speck of gold amongst the landfill of crap our TV programmes are. But it encourages me to read more books, so there is a plus side.
It may well be available via the BBC iplayer if you missed it.
