Doing a bit of research about what happened to the main players, found out that Bill Fraser (who I think is great!) was married to Pamela Cundell of Mrs Fox fame, who used lean over Jones' butcher counter with her ample bosoms and ask him if she had enough. Never fails with me.
The only thing I can't find anything about is who the pretty girl is who features either side of the advert break and as it happens is slap bang in the middle of the thread photo above, just to the left of Bill Fraser and in between the two suited producers (?)
Real long shot here, but does anyone know? No mention of her on the IMDb.
