Sir Elton John has spoken about his incredible friendship with late Beatles legend John Lennon.
The stars of the music world shared a wonderful friendship which Elton has described as "whirlwind romance".
Music icon John's life was tragically cut short when he was shot and killed by obsessed fan Mark David Chapman in New York City on 8 December 1980.
If he were still alive today, John would be turning 80 on October 9, and BBC Radio 2 is paying tribute to the legendary musician and peace activist with a series of moving interviews from those who knew and loved him.
In a two-part interview broadcast this weekend, Elton said they had a "whirlwind romance" of love, friendship and music.
Speaking to John's son and his godson Sean Ono Lennon, 44, Elton gushed: "That was the kind of wonderful two or three year whirlwind romance we had and it was such such an important thing in my life, Sean, and it just really helped me.
"It gave me so much confidence. Your dad was as kind and as generous and sweet and we just hit it off immediately."
The duo met in person for the first time in 1973, and Elton was thrilled to meet one of his heroes.
Sean revealed that the feeling was mutual as he told Elton: "My dad, when he first heard your voice he was in America I think already, and he was thinking that's the first new kind of British singing that he really liked and dug. I think he said that he loved your music and the songs and he liked the song, Your Song."
Elton said: "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."
The stars had a close friendship over the next two years, and Elton even played on John's fifth album, Wall & Bridges on his track Whatever Gets You Thru The Night.
Lennon also starred alongside Elton at his iconic Madison Square Garden concert in November 1974.
