ROLLING Stones guitarist Keith Richards once mixed his father's ashes into a line of cocaine he snorted, he told British music magazine NME. "He was cremated and I couldn't resist grinding him up with a little bit of blow," he said, quoted in the music weekly's latest issue. "My dad wouldn't have cared, he didn't give a sh--." His father Bert died in 2002, aged 84, and was cremated. Richards said his ashes were pleasant to snort. "It went down pretty well and I'm still alive."
