Sixties singer PETULA CLARK "dabbled" in drugs at the height of her fame, but prefers a less dangerous glass of wine. The Downtown star, 74, came into contact with illegal substances at the many showbiz parties she attended. She says, "I've dabbled, though I usually prefer a glass of wine. "I'd go to parties in California where the likes of Marlon Brando and Miles Davis were at and you'd get stoned simply from breathing the air. "I find the whole thing rather silly. I can't remember the last time I tried anything and I've never been tempted to get more involved."
