I don't see much evidence of a folk process here in Arizona. People don't sing to each other except at Karioke bars, where the folk tradition is short circuited by having "canned" music and follow the bouncing ball lyrics on a TV screen. The few places where you can see live music usually have folks from New Jersey dressed as cowboys playing music with pre-recorded rhythm tracks and Fake books - so they can get it "right" (meaning as recorded so the tourists will leave big tips!) Kind of horrible. Our pop culture seems bent on leaving behind anything of worth and replacing it with campy trash or "original" music which steals from the tradition without understanding it. I hope there are pockets of culture where people still sing traditional songs to each other, and sing them often enough to take ownership and add/subtract lyrics, modify melodies, etc.
