During a Radio 2 special to celebrate Lennon’s 80th birthday, Elton describes an incredible two-year period that followed, filled with laughter and creative exchanges where Elton played on John’s fifth album, Wall & Bridges, notably on the track Whatever Gets You Through Night.

John guest starred at Elton’s legendary Madison Square Gardens concert in November 1974 where they duetted on the aforementioned track, among others. WATCH THE ONLY KNOWN FOOTAGE OF THEM BELOW.

Elton said of the whole experience: “It was just, for me, it was a dream come true.

“We laughed so much because we talked about the 50s and 60s and where we grew up, you know, Round the Horne in England, the radio shows we liked, the songs we liked, we didn’t like, and your dad was just a fountain of knowledge. It was a hand in glove thing and I never thought that would ever happen.

“There was no attitude. I hate posers and I hate attitude and your dad didn’t have any of it.”
