"There's a drumming noise inside my head whenever you're around. It's funny you can't hear it, it makes such an almighty sound."
For the past several weeks I've thought it was a song about the Master from Doctor Who and the drums (here come the drums here come the drums!) he hears in his head. J helpfully pointed out that it was probably referring to her own pulse in her head, not an episode or 5 of Doctor Who. Whoops, guess I just really love that show.
