Elton John and Lady Gaga are teaming up with British musician Sting for his upcoming Rainforest fund benefit. The event will mark the 21st birthday of the charitable organisation, which Sting and his producer-actress wife Trudie Styler founded. "She's (Gaga) such a great young woman. It's a winning combination -- we're going to have a riotous time up there," contactmusic.com quoted Styler as saying. "Sting, Elton and Gaga will play together, and the boys will be performing with Dame Shirley, doing a great rendition of Hey Big Spender." The trio and Dame Shirley will perform together at Carnegie Hall in New York May 13.
