Sir Paul McCartney remembers fallen Beatles John Lennon and George Harrison every night on tour when he pays tribute to his tragic bandmates.

The singer takes an emotional trip down memory lane at each date on his On The Run Tour when he performs The Beatles hits, including their 1969 ballad Something, which was written by Harrison.

He tells British magazine Radar, "Pretty much every night on the show (I think of them) because I do tributes to them. I have big photographs of George behind me when I do the song Something, his song, and I look at them, and it's so sad because he's not here.

"But it's lovely to look at those pictures and think, 'God, my mate George, isn't he a good-looking boy!' You think all the things you couldn't think when you were a kid, because the bravado aspect forbade it. I do think of them quite a lot."

Lennon was shot and killed in New York City in 1980, while Harrison lost his battle with cancer in 2001.
