Stringsinger, there are definitely lyrics to South Wind. Archie Fisher recorded them on his wonderful(and still available)1977(?)Folk-Legacy record, "The Man with the Rhyme."

Glad this thread has been resurrected. I'm leading a workshop at the NEFFA Festival just outside Boston, Mass. in April 2009 called "Waltz Time." I've billed it as "Songs about waltzing--or that you could waltz to". The list is long!
