The caller asked at the pre-break announcement. It was an "open-band" for all comers - I'm not currently in a contra dance band though I was until last year.

I've known the other musician for a while. He does seem to have strong opinions and has gotten prickly about things before. I think it was his attitude and tone of voice that really irritated me- and then just turning away after having made his point.

Thanks for letting me vent!
