I recovered an old 1990 Sky Movies recording earlier, and now I've got the theme tune stuck in my head. That thing's a bloody earworm. I'd love to know who made it and what it's called. (the idents were - I think - made by PDI)

@philpem that whole set of idents and themes (and the following tombstone idents) are just iconicly 90s!
