I will break this to you very gently as you are a Big Al - I just phoned my mum and she has already recorded over the top of it. Soooorrrrrrrrreeeeeeeeeeee!!!!!!!!!!!!!!!
Why do mums do that - she's got blooming 100's of DVD's in her house but no she tapes over the Doc!!
You could try and put a plea out in either media or body and soul for anyone else who may still have it!
:o(
ps the only good thing is it didn't have a Christmas theme and could be shown any time of the year so chances are it will be on again shortly.
