There is quite a lot of stuff in the BBC archives, the best of which is the Jake Thackray and Songs series from 1981 (On Again On Again and The Bull in the documentary came from this series) and The Camera and the Song from 1973 or so. There is also material from Braden's Week, That's Life and the Dora Brian Show(!) as well as some other odds and ends. There is also likely to be more which is misfiled.   Those of us who are behind the www.jakethackray.com website have copies of most of it as well as some other odds and ends. We've put some of it out but are trying to do so in a way which ensures appropriate royalties go to Jake's estate. We also have some good soundboard recordings from gigs and some video material which we plan to release in due course (ie when the day jobs don't get in the way)
   As I mentioned in an earlier post, the main issue with the BBC (who are otherwise very helpful) is the commercial structure which is in place for licensing archive material. If we can crack that then we can get the material out to those who appreciate it.
