The prevailing view seems to be that song beloved by so many began as a chantey, but I have never had the opportunity to hear it performed as a chantey. I have a chantey version in the song book "The New Song Fest", Dick & Edith Best, Eds.,1948, 1955, 12th Prntg, 1962, Crown Publ.; Lib.of Cong. 54-12069. Might have to give it a try. Ives' categorization of it as a "short haul chantey" might reflect the fact that the Shenandoah isn't a major river. As I recall, it's a tributary of the Potomac, and does not connect to the Ohio, which would be necessary to reach the Missouri by river.
