Geoff and Maria Muldauer sang this song on an album issued in 1972. A Japanese company has re-issued the album in a limited edition cd of the title, "Sweet Potatoes." Only ten tracks, and listed at US$51.99 by Amazon.com.

"Sweet Potatoes" was a ragtime March (slow drag) composed in 1906 by Justin Ringleben, Seminary Music Co., NY. Sheet music at the Univ. Colorado (Boulder) Digital Libraries. NO lyrics.

I doubt that either of these has anything to do with the Seeger etc. song.
