John Lennon made his final onstage performance with Elton, when he joined him at Madison Square Garden on Thanksgiving Day in 1974. Lennon's appearance was the result of a bet that if his song Whatever Gets You Through The Night - which featured John on harmony vocals and piano - went to number 1, he'd join Elton on stage. It did - and he did.
Elton has many pieces of advice for touring, chief among them that "It's very important to have two tiaras when you're on the road. You never know when you'll be invited to something really formal."
