EUREKA !!!
A 'net auction site by the name of eBay had one VHS PAL version for sale and I was the only bidder at the reserve price of £7.99 (plus £2 p+p).
Annette was extremely pleased to finally have a copy, not pleased enough for a bit of nookie, but she did say she'd make me a copy
Anyway, she asked me to pass on her thanks to the 'Cat for all the interest taken in the search. So on behalf of Annette, and myself, THANK YOU ALL.
Mike
