At the orchestra concert we always like to have a few small ensemble numbers. Noah’s quartet played, but we were short on other stuff so I told my family we’d play something. This was the first time we’d performed as a sextet, with Fiona as well. We had one fifteen-minute rehearsal plus a run-through in the hall. It came off pretty well, I think. The tune is “Danny Boy,” a.k.a. “Londonderry Air,” a.k.a. “London Derrière,” a.k.a. “London Butt” (by my kids — who else?).
