In the late eighteenth century and early twentieth century collectors of traditional songs and tunes would sometimes find white mountain people who had "gotten religion" and would no longer sing or play the old songs and tunes which they came to regard as "the devil's ditties". While some people continued to keep the old traditions alive with house parties, barn dances and frolics, the more religious refused to allow their family members to participate. Younger members of these families found a loop-hole that came to be known as the "play party" where, while dancing was prohibited, singing games were not. As the evenings progressed, some couples would begin to actually touch and change partners much like dance moves. The music is much the same as the dance tunes but with words. "Swing and Turn Jubilee" is one such play party song. It shares some verses with "Shady Grove". Alan Lomax recorded it by Jean Ritchie in 1949 who would have played it on dulcimer. In The Folk Songs of North America the title is given as simply "Jubilee". It plays easily on both dulcimer and banjo. I learned it from the singing of Carolyn Hester. I can't remember anything else about her except that she was Bob Dylan's girlfriend for a while. I think it was also incorporated into "Celebrations for a Grey Day" by Dick and Mimi Fariņa.
