The "Flavia" theme (which I guess is going to be a lot more common as a name, now the the Doctor has a new, exclusive personal theme) is this one. It plays after the Doctor walks away from Rose, rather than during the speech, but it's probably what you're thinking of. [yt]http://www.youtube.com/watch?v=fxlG15BcCyE[/yt] The producers apparently thought it sounded like Flavia, and the name stuck. Looks like the last time we'll ever hear it is the start of Ten's regeneration. ETA: That's weird. Half the post vanished when I edited it. Doubly so, because I checked it after I edited it, and it was fine. Maybe I used the back button when I shouldn't have. Anywho, I've recreated it.
