The Beatles' success was largely driven by the songwriting prowess of Paul McCartney and John Lennon. They were the dynamic duo behind the band's phenomenal success, whether they were co-writing or independently crafting songs before sharing them with each other.

Another song which the Beatles legend finds particularly moving is Billy Joel's 1977 single 'Just The Way You Are'. Written by the New York native as an ode to his wife, the song is one which Paul said he wishes he'd written.

During his surprise show in New York City at the Bowery Ballroom, Paul McCartney played songs from his Beatles, Wings, and solo discography throughout the setlist. However, one song particularly stood out.
