So I’m watching 27 Dresses this weekend, and after the bar sing-along scene to Elton John’s “Bennie and the Jets,” I find myself momentarily distracted and wondering how often an entire bar erupts in song. Has it happened to you? I’m talking about the whole bar, not just you and your friends belting out the “I’ve seen a million faces, and I’ve rocked ’em all” line of “Wanted Dead or Alive.”

I myself have experienced this phenomenon only once. About 10 years ago in San Diego, at a piano bar called Albie’s Beef Inn. I was with my sister and two friends. We didn’t want to drive and the bar was next to our hotel. We walked in and were the youngest people there by 50 years. We said, “Either we leave now, or we get drunk immediately.” We ordered shots. I remember singing “All of Me” and “The Very Thought of You” at the piano (which my sister informed me the next morning was actually a Casio). We ended the evening in an all-bar sing-along — and kick line —to “Those Were the Days.”

Your turn.
