Under the right circumstances, I’m a huge fangirl, and last night’s Rufus Wainwright show released the stars . . . It was more greatest-hits than I’d expected, lots of stuff from Poses, opening with “The Art Teacher,” and a scorching version of “Going to a Town.”  And – as every fangirl or -boy does – there was the moment when he played the song I was hoping for (two, actually – “This Love Affair” and “Rebel Prince,” both of which are on heavy rotation as I write Part 2), and I peeped in ecstasy like a just-born chick.  What a voice.
