Charley,

Pinch o' Salt recorded their version of this poem turned song on a CD called "Handspike Gruel and Seaboot Duff." Danny McCloud was part of the group -- can't recall who else was in the trio. Could be they never actually released the recording. It's all CF Smith lyrics, with tunes by one of the group's members.

I've never come across "Sou' Spain" -- the expression -- anywhere, either.
