Lucius, I think there's a barbershop quartet arrangement of this song. I don't think I have it, and all my books are in boxes now and I can't look. Look around at http://www.spebsqsa.org/ and see if they have it. If you don't find it, send them an e-mail.
My Scoutmaster was a barbershopper, so I grew up knowing that SPEBSQSA means the Society for the Preservation and Enrichment of Barbershop Quartet Singing in America, Kenosha, Wisconsin.
