PETER SEIGEL PLAYED his fiddle in Mother’s in Friday night. Seigel—singer, song writer, and political voice—entertained audiences with his songs and his satirical humor. Long an activist for the New England region, Seigel took time from his busy schedule to play a few tunes for RPI students. His next performance will be at the Adirondack Dance Weekend, in Lake George, NY, from October 3 to October 5, where he will be accompanied by Beverwyck, a string band.
