Lennon/ono Concert Reunion Landed Elton John Godfather Role

Lennon had split from Ono while he was recording Whatever Gets You Through the Night with Elton in 1974, and the couple reconciled when the Rocket Man star persuaded his pal to join him onstage at a concert in New York.

Elton landed the Lennon guest spot at a show after betting the Beatle the album they had worked on would hit the top of the U.S. charts - and it did.

He recalls, "I said to John, `I'll play on your record (but) if it goes to number one, you have to come onstage with me...' He never thought the record would go to number one."

Introducing Lennon onstage and playing live with his hero made for a magical night for Elton.

He adds, "I'd never heard a reception like it... It was such an incredible outpouring of affection.

"That was the night John and Yoko got back together. They remet at that concert and that's why I became Sean's godfather."
