Dear davidg,They must've spelled it that way 'cuz they're Yankees ;-)
I went searching on the 'Net and I found this great link, with a description of Pokeweed, the lyrics and the same midi file for the song, AND a recipe for POKE SALAD.
And FYI - Where I come from, 'Polk' is pronounced the same as 'Poke' . . .
All the best, Áine
