I think the Folk Process is clearly surviving in what people call "Mondegreens(sp?)" Or misunderstood lyrics.Even in copyrighted material this is apparent. For example, if you look up Phil Ochs "No More Songs" online, there seems to be a difference of opinion in one line in the last stanza.Some people think it says "he waivers on the beat, he's dying" others think it is "the whale is on the beach, he's dying". If you listen to him sing,in most cases it sounds like he is saying the interpretation about the whale, which fits with a reference to " a white bone in the sand" in other words beach imagery is being used ( there's also the fact whales also sing)But Mudcat's lyric archive has the "waivers on the beat"version. I learned the song from Leslie Fish,who wrote a mythic/ allegorical Phil Ochs tribute called " Chickasaw Mountain" and she sang the whale version. I actually found it touching, considering the helplessness of beached whales, and whalesong.I sang it that way for years, but at one event someone actually burst out laughing yelling "whale on the beach!" How rude!This is an example of the folk process in my opinion.
