"Jazz fit right in with Prohibition. Like acid rock in the '60s, it became a banner. 'I like jazz' = 'I drink'—and dance, swear, fight, make love without benefit of a license, live—whatever, as long as it ain't Victorian. The 'jazzhead' creed was no more consistent or coherent than that of their grandkids forty years later, and it raised the same kind of hackles."
