The other day someone discovered that I play guitar, and asked me to play something. I froze. I realized that I can play a lot of songs in a band situation, but I don't have anything that immediately comes to mind when asked to "play something." I finally decided on Little Sister, but by then, the conversation had moved on. I also realized that "play something" usually means "sing something." Do you have a "go-to" song for those moments when someone asks you to play something?
