Steve, this is a very rare title, probably owing to the fact that the ending features several of the cast (not VP) in a "blackface" vaudeville musical finale. Not exactly "politically correct" nowadays... Good luck!
I have this title on region free DVD, which I transferred from my own VHS recording from Channel 4 in the UK. It has a nice clean picture and colour, although the sound is slightly out of sync as it was my first attempt at DVD encoding.
I can do copies for £5.00 a piece, plus postage and packaging via Paypal if you are interested.
.. do you have contact details for Peter who posted a response to your comment about the cc@cc movie ? I too am keen to obtain a copy - it's a great movie and I haven't seen it for eons ! !
