I have previously been in touch with the BBC archive department about long lost folk radio shows as part of the Treasure Hunt appeal for missing TV and Radio programmes and also for episodes of "Ballad of the North West" that was broadcast on BBC North West (nothing survives of that unfortunately although rumours of private audio tapes have come to my attention.)

The address to write to for queries is:

BBC Archives
Windmill Road
Reynard Mills Estate
Brentford
Middlesex
TW8 9NQ

I'm not sure if BBC Scotland have a separate archive but someone should be able to help.

Whilst they can tell you if a programme still exists or not please be aware that they are unable to supply copies of programmes to people. "If it's not out on Video or DVD then we're afraid that we're unable to supply ad hoc copies"

Good luck with it and please let us know how you get on.

Cheers

Mark
