I would like the to add the way Paul speaks about Art in the second part of In restless dreams too. Specifically the bit where he talks about working with Art on Hearts and Bones (before his part got scrapped). Paul just seems so hurt about his relationship with Art and this is probably how he copes with it?
"We do not refer to Beatles songs as early Paul McCartney songs or early George Harrison songs. They are Beatles songs. (...) Rolling Stones songs are not referred to as Jagger's or Richards’s songs. Ray Davies wrote most of the Kinks’ songs but we do not call them early Ray Davies songs. The songs of Simon & Garfunkel were a collaborative effort, and are distinctly different from Paul Simon’s successful solo career. The works of Simon & Garfunkel have won many awards in the name of Simon & Garfunkel. They are in the Rock & Roll Hall of Fame in the name of Simon & Garfunkel." "Art Garfunkel was Paul Simon’s missing ingredient. Without him you’ve got smoke but not the explosion that was Simon & Garfunkel."
Thanks fuck somebody said this. Bravo.
