Roughly 70 years ago, a young James Paul McCartney wrote his first ever song at the age of 14 on a £15 Framus Zenith in the latter end of 1956, titled “I Lost My Little Girl.” Today, Paul finds himself back in the studio, preparing to release what will be his 18th album, Boys of Dungeon Lane. In preparation, McCartney released the first single off the album, and his first single in 6 years, “Days We Left Behind.”

Unlike most artists, McCartney treats his first single as a door to the album, not a blueprint. The project is expected to focus on his upbringing in war-ravaged Liverpool, but not necessarily as an acoustic, stripped-down folk record. Reminiscence has never been new territory for McCartney, but his approach to it has evolved over time.

Going back to late December 1966, McCartney sat homesick in his London home at 7 Cavendish Avenue, where he wrote the iconic “Penny Lane.” In contrast to “Days We Left Behind,” “Penny Lane” serves as an upbeat, almost surreal tribute to life in Liverpool, likely shaped by what McCartney missed most about his hometown.

Now, with days gone by and friends grown old, McCartney returns to his roots with a slightly wiser perspective on his childhood. Drawing from lyrics that date back to an unreleased demo track called “In Liverpool” from 1991, which he later performed at The Liverpool Sound Concert in 2008, Paul originally wrote, “Walking with the boys of Dungeon Lane / Aimlessly towards the cast iron shore.” These lines have now been reshaped to fit the perspective of his older self as, “See the boys of Dungeon Lane / Along the Mersey shore.”

With time, Dungeon Lane has grown more distant from McCartney. Instead of walking with those boys, he has grown apart from them. Now, he simply sees them, not beside him but as a memory, something far removed from what he once wrote.

The meaning of “Days We Left Behind” comes into full focus through its evolving chorus. While each refrain lands on the same sentiment of “days we left behind,” McCartney reaches it through a progression of thought, moving through lingering ideas about changing times and why things may have unfolded the way they did. This reflection ultimately settles in the line, “’Cause nothing stays the same and no one needs to cry, no one is to blame for the days we left behind.” It’s a quiet moment of wisdom that feels true to McCartney’s nature, an understanding that time moves on and there is no one to blame.

With Andrew Watt behind the boards, the production of “Days We Left Behind” stays minimal, a common preference among McCartney’s recent solo work. Watt, who has become a go-to name in the industry in recent years, has consistently served as a catalyst for some of the best in the business. While many producers lean into a signature style, Watt focuses more on bringing the true nature of each artist to the forefront, and he does exactly that here with Sir Paul McCartney.

“Days We Left Behind” doesn’t try to recreate the past, but instead comes to terms with it. At this stage in his life, McCartney isn’t looking back with regret, but with an understanding of how those moments shaped him into who he is today. It stands as a reflection not just of Liverpool, but of time itself, and the quiet realization that while nothing can bring those days back, there’s no need to. In many ways, it feels less like a return and more like a final acceptance, a full-circle moment from the boy on Dungeon Lane to the man looking back on it all, as "Boys of Dungeon Lane" arrives May 29th.
