This looks like a really great idea Mo. Trust it goes well. We tried something similar last July and it went really well. The Band grew out of our tunes session - we had 28 in the band on that night and our own caller. He had a radio Mike and we played accoustically. Great fun. We have played 2 accoustic ceilidhs since with our caller and one guest.

Best wishes from The Beech Band
