This has such a taoist quality to it, as if simply by talking about folk music or singing a song, it isn't the real folk song we're singing. I change other people's lyrics all the time, I just forget a certain lyric and say something to fill the space, or I learn off of someone's tape and misunderstand a word. My understanding of Woody Guthrie's oft-repeated quote is that folksingers naturally steal things like tunes and lyrics. To me, the phrase the "last true folk song" is an oxymoron--and it seems (again, just my perspective) a bit short-sighted to believe all of us aren't in the folk process continually, like stones being tumbled about by the sea. I'm not sure we have much choice in the matter, to be honest.
