LONDON — An anonymous buyer snapped up a lock of Mick Jagger's hair for 4,000 pounds ($6,000) after bidders pushed the price to double its pre-sale estimate, auction house Bonhams said. The clump of hair was sold by the Rolling Stone's former girlfriend Chrissie Shrimpton, who is also the sister of 1960s English model Jean Shrimpton and first met Jagger when he was still an unknown student at the London School of Economics. — Reuters
