I did not realize all of this was art

Of course it's art. Why wouldn't it be art? Much of the revival has appointed itself the custodians of some of the greatest works of art ever realised in the form of Traditional Folk Song & Ballad which are the work of exacting mastery, not the random byprodcts of fun, recreation, pleasant sensations. Of course this doesn't preclude any of the foregoing in the sharing of our passions (same goes for any Art) but if that's just an excuse for dumbing it down to common-minded strum-a-long renderings of The Wild Rover or (Lord save us!) The Fields of Athen-fecking-ry then chances are you'll find me at the bar discussing the finer points of Pasolini's Life Trilogy with the landlord.
