So are your sarcasm quotes.
The Vietnam police action went on for twenty years. Forty five years ago was near the end, probably past the pragmatic end.
That the musically inclined offspring of plutocrats would form a clique, and meet somewhere is somewhat unremarkable. Bikers go to Sturgis, Laconia, Red River and Laughlin, shooters go to Knob Creek, Camp Perry and Buffalo Creek, cow culture flocks to Cheyenne Frontier Days and the Denver Stock Show and so forth.
It seems like the article's slant has the tail waging the dog. The minstrels were a product of the culture, more so than multiplicands or divisors.
There's little irony in David Crosby packin. The old CSNY joke (partially fueled by some of the band members becoming calorically challenged) was "What weighs more, Crosby, Stills, Nash and Young or the Queen Mary?.......................trick question, when they're fully armed they weight the same."
Frank Zappa's passion was classical music. Upon his death, they found thousands of hours of sixteen track recordings in the environmentally controlled labyrinth beneath his house. It's still being released and not uncommonly heard on classical music radio stations. Like any good crapitalist, he let the invisible hand guide him, writing songs about titties and beer and the devil.
I suppose that the lime light on an unfortunately violent narcissistic cult in the vicinity added to the notoriety. In the light of modern jihad-ism, it too seems sort of minor.
