Mussehl and Westphal is one of the oldest musical saw makers in the United States. They have been making beautiful saws since 1921, and in the old days the company produced small records on the Flexo label to advertise their product. These records were small flexible plastic records, and they came in a variety of colors. Here’s a short recording of a saw duet, two saws playing “Old Folks At Home,” also known as “Swanee River.”It’s very difficult for two saws to play harmony and this is an impressive performance. It’s short and sweet.
