“Instead, David was sitting on the floor with an art pad and a charcoal and he was sketching things and he was completely ignoring Lennon.
“So, after about two hours of that, he [John] finally said to David, ‘Rip that pad in half and give me a few sheets. I want to draw you.’
“So David said, ‘Oh, that’s a good idea’, and he finally opened up. So John started making caricatures of David, and David started doing the same of John and they kept swapping them and then they started laughing and that broke the ice.”
David and John continued to be great friends, and on tour in 1983 David performed Imagine, before which he spoke of his friendship with the Beatles star.
