Can any1 id a choon by its main theme?

Help wanted - heard a choon some time ago but I don't even have a sample of it for iding. Thank god the theme was too damn catchy, so I managed to restore the most memorable moment from somwhere deep within my brain.

Any ideas what it could be?

Thanx in advance.
