The show's theme, of course, but since that's the obvious choice, I'm going to go with something else: an incidental throwaway of Murray Gold's from "Gridlock" called "Gridlocked Cassinis." Murray can be terribly schmaltzy at times (and please, Moff, don't ever let him write song lyrics on your watch), but "Gridlocked Cassinis" is a light-hearted bit of early 60's-style cocktail jazz fluff -- if you like Combustible Edison, you're probably going to like this, too.
