George and Tom,

Thank you for your help! Portsmouth won't work out for us this time around due to timing and geography, but it occurs to me we should just come up some other time. It's not that far from Boston.

Meanwhile, I found a Web reference to an occasional song swap on Wednesday evenings in Damariscott (really close to Bremen) at the Salt Bay Trading Company on Main St. If I learn any more about it, I'll return the favor and update the thread with that information.
