'Bout a week ago I panned the episode (see "Sanctuary jumps the shark"). I wasn't boggled so much at the thought of a musical TV episode as a sci-fi musical episode. Musicals are one of two genre I think of as at opposite ends of the entertainment universe from sci-fi (the other being romance [and thus I was impressed by epic romance between The Doctor and Rose]).

I think part of my initial reaction was just disorientation at the genre-bending. And I really wasn't at all boggled by the premise, which was just that, a thin excuse to try out somebody's Gilbert and Sullivan fantasy. I've heard of that kind of dysphasia(?) before, actually. Something about speech centers damaged and function rerouted through formerly musical brain structures.

Entertaining story about Bishop and Tillis, too, thanks for tossin' it in.
