I vaguely remember this being a pretty good collection of BBC session tracks:
Led Zeppelin are to release ‘The Complete BBC Sessions’, which includes a song not heard since it was first broadcast in 1969.
The 33-song album features a three-song session from March 1969, which had been unheard since it was first broadcast the following month. A fan who taped it from AM radio in Europe has come forward with a recording, which has been restored to releasable quality by guitarist Jimmy Page.
The session features the only performance of ‘Sunshine Woman’, which Led Zeppelin never otherwise recorded, as well as ‘I Can’t Quit You Baby’ and ‘You Shook Me’.
They've expanded this set to make it more "complete" after putting it out about twenty years ago. What's changed is that there is a market for the vinyl release, and so they're going to go after that without regard for anything else. I'll probably acquire it by default, but, really--there are a slew of great Zeppelin shows that have only ever been available as bootlegs. Why not put those out instead?
Still missing is a complete accounting for everything that the Police did on the BBC (several concerts, numerous sessions, things of that nature) and an official release of BBC sessions by the Verve. I am a huge fan of the Ride and the House of Love releases, so we need more of this to come out. If you don't have the Jam or XTC at the BBC, you should probably get all of that, too.
