'The rockocracy is moving into wine,' reports JONATHAN RAY. And some of it might actually be quite good. Cliff Richard's Vida Nova from the Algarve was apparently too successful for Tesco, which has declined to stock the current vintage 'not because it is no good, but because the winery can't produce enough to satisfy the supermarket's demands'. Although, speaking to Bruce Cohn of the Doobie Brothers, Ray sees the downside of this hobby for the rockers. Cohn says, 'The great tragedy is that half the band haven't tasted [their wines] and never will. They drink only Perrier now, thanks to their past excesses.' Ray looks forward to a Chteau Oasis in the future.
