Tennant says he'd be up for one of his final four specials to be a musical, but that John Barrowman is most excited about the prospect. Well, given that the dreamy Captain Jack portrayer has a gorgeous singing voice and oodles of stage experience, I'm not surprised. And of course there is speculation that a musical episode might mean that Billie Piper would be back, given that she's a former pop star. Though after that gut-wrenching season finale lord only knows how that could/would happen. Even if it doesn't mean more Rose, I'm excited at the mere possibility of this happening. The Buffy musical episode is one of my personal favorites and I trust that the Doctor Who PTB would come up with something that could rival it. Oh, if they could somehow find a way for Capt. John Hart (played by James Marsters) to stumble into this melodic mix, that would be incredible. My head might explode, but it would be worth it.
