Although K & I met through community productions of G&S, we never actually did a show together. The closest we ever came was when she teched a show I was in, or I once loaned several sets of finger cymbals and a tambourine to a production of Patience that she was in. Apparently we look just enough alike that at least one friend thought at first that we were the same person. :D (He once complimented her on "her" performance in a show that I was in; she had to sit it out.) As a result, we used to joke that we were matter and anti-matter; should we ever manage to appear on stage together, it would be the end of the world.
Well, K was in town for the G&S Sing-Out this weekend. She mostly sat in the audience drinking in the music or hung out in the lobby getting caught up with friends she hadn't seen since she moved out of the area years ago. But yesterday morning, before she had to leave to go back, she & I sat on stage, together, singing the Yeomen of the Guard choruses from a shared score. We even have pictures documenting this momentous occasion.
So it's happened - we have now sung on stage together! You'd better make sure your will is current and the rest of your affairs are in order, as the end of the world is just around the corner.
