Jam

Yesterday we went to a "jam" at one of the parks in the area. This is an activity one could engage in nearly every day of the week, as there are dozens of them in the area.
Basically, a bunch of old people bring their instruments and or their voices and regale one another with song. The quality ranges from very good indeed to nerve jangling. We enjoyed it.

These Minnesota gentlemen played
two of the three concertinas present.
