This is one of Charles Dance's early screen appearances (he only made his debut in 1974, here in an advert for Dry Sack Sherry from 1977. It wasn't until I got a close up of him and heard his voice that I recognized him, but it is definitely him behind the mutton chop whiskers (the ginger haired chap) showing a young lady in period dress down a wine cellar. Oo er!
