Tiny Tim is back--again--and this time Nashville's got him. The tremelo-toned croonster, whose 1960's hit "Tiptoe Through the Tulips" and televised marriage created an international sensation in the 1960s, is embarking on a career as a country music singer. He's released a single for the Nashville-based NLT Records entitled, "Leave Me Satisfied," and label president Gordon Stinson is convinced that the entertainer will be greeted warmly by country music fans. "It seems like things come around in 20-year cycles," Stinson said. "I think Tiny's about to find himself current again."
