I can remember quite clearly sitting in a session some years ago and an accordionist played Southwind, probably in the key of G, followed by another waltz. I can remember the pub I was in, who I was with and some other stuff not pertinent to this request. What I can't remember is the tune that came next. It was a waltz. It had two parts. I suspect it was in the key of D. In the second part, first time through, what I expected to be an Em became E major. The second time through it didn't. Can anyone suggest what the title might be?
