Hmm, well, I'm musically in love with Rufus Wainwright.

I figure that Momiji would appreciate him. And probably be one of those concert-goers who would be squirming around in his seat and half-singing along and being borderline annoying.

Horatio and Ganymede would be baffled and probably neutral. And just sort of sit there.

Dahlia would probably just dislike him and walk out to find a beer.
