SN...offered a fan a sip from her wine glass...

[Livia]

The first time I ever heard a firsthand report of a rock show was from my science teacher, a bitter, overtanned thirtysomething who had just seen Fleetwood Mac and thought it was so amazing how Stevie Nicks, mystical shawl billowing, had walked over to the edge of the stage and offered a fan a sip from her wineglass. Wine. Typical. It made complete sense. The biggest-selling rock album of 1977, Rumours, was produced by rich, luxuriating hippie sophisticates who cavorted like sprites and nymphs and sipped chardonnay.
