All it takes to keep Elton John's tiny dancers dancing is a little cocaine, the singer says in a new documentary Madman Across The Water: The Making Of Elton John. Three Dog Night's Danny Hutton "might have forgot to tell him" about he sprinkled the singer's dinner to keep him playing the piano at a party. "I left at 7.30 in the morning and I thought, 'I've never stayed up until 7.30 before but I feel really good!,'" says Elton. "Years later I learned they had put cocaine in my food." And all along I thought Elton's stamina was derived from checks with sizable zeroes.
