My introduction to American Folk Music festivals (and the lack of drink, thereat, but that's another sad story)was when Barry Finn took me along to Sing into Spring at Tufts University in the mid-80s. Instead of swigging down beer between songs, the Greater Boston Folk Song Society had taken up Analyzing in a big way. At one workshop they managed to debate themselves into paralysis, over the meaning of "wan" which had cropped up in a song in connection with the water quality of an obscure stream or the pallor of a damsel's skin, or somesuch....I wandered off, in search of "wan" decent pint. Anyway, I nominate "wan" for a place in the Top 100, in honor of the linguistic boffins of GBFSS.
