Paul McCartney, now 83, reflects on the enduring influence of his former bandmate John Lennon on his songwriting, even decades after Lennon's tragic death in 1980. Their friendship began in their teens in Liverpool, where they bonded over personal losses. McCartney's recent album, The Boys of Dungeon Lane, showcases this nostalgia, featuring songs that reminisce about their early days and the Beatles' legacy. The album includes the single 'Days We Left Behind,' which addresses their complicated relationship post-Beatles and expresses a sense of reconciliation. McCartney acknowledges that he often considers what Lennon would think of his music, saying, 'I can gauge his reaction: that’s good, stick that in.' The album also pays tribute to George Harrison, with McCartney recalling fond memories of their time together. With contributions from Ringo Starr, McCartney's latest work is a heartfelt homage to his fellow Beatles, ensuring their spirits remain a part of his creative process.
