Thanks Camus - ominous bit of music that!
Funny, every time one of my particular friends and I see one of those dodgy vans driving around, we always say "yep, there's someone tied up in duct tape in the back of that one!" Now we have the soundtrack for our little in-joke.
p.s. - Pear-shaped? That's the 2nd time this week I've heard that phrase . . .
