Interesting question, and with all due respect I think that you're all pretty much missing the point.

Folk Music is about the human condition

Sure, "The Times They Are A-Changin" may not have the same resonance to these kids, but find me a teenager who doesn't relate to:

And don't criticize
What you can't understand
Your sons and your daughters
Are beyond your command

Plus ca change, plus ca la meme chose...

If it were my gig, I would concentrate on songs that illustrated these things.

I would play "We Shall Not Be Moved" and "I Ain't a Marchin' Anymore"

I would however try to explain that they were songs written by ordinary people who were pissed off with the status quo and wanted to change things.

Hope I've made my point well enough to be understood.

PS

These sleeve notes from a Martin Carty LP maybe reinforce what I'm trying to say:

Latterday equivalents of the leading characters in the great ballads still appear in local newspapers today: the enraged husband who thinks his wife is unfaithful, the lovers who wait for each other through years of separation, the woman who kills her own illegitimate child, the girl who prefers to die rather than submit to an arranged marriage with a man she hates, the incestuous and jealous brother, and so on.

These are still very much with us, even if they are not necessarily members of the aristocracy and their steeds are made in a Japanese factory and live in garages rather than stables these days.
