On a night in the autumn of 1968, Paul McCartney fell asleep in his house in St. John’s Wood, London, and his mother came to him. Mary Patricia McCartney had died of cancer in 1956, when Paul was fourteen. By 1968, she’d been gone for twelve years, and McCartney had become arguably the most famous musician alive. It didn’t make missing her any easier. In the dream, she came to him with a phrase: “Let it be.”
That autumn was also when the Beatles were falling apart in slow motion – John Lennon had become inseparable from Yoko Ono, the business was turning adversarial, and the “White Album” sessions had been rather tense. McCartney later described that period as a very difficult time, saying he could sense the Beatles were breaking up and that he had fallen into a pattern of late nights, drinking, drugs, and clubbing. He was also the only one of the four still living alone in London, without a partner, which he mentions in the same account.
The Dream That Gave McCartney “Let It Be”
Then he fell asleep, and Mary appeared. In Barry Miles’s authorized biography Many Years from Now, McCartney recalled dreaming vividly of his mother, Mary, who reassured him with the phrase that would become the song’s title. He woke up feeling better. He went straight to the piano.
There are actually two origin stories for “Let It Be,” and both of them are true. McCartney has told the dream story consistently for decades. But when he first started messing around with the song in the studio – during a break from recording “Piggies” on September 19, 1968 – the lyric wasn’t “Mother Mary comes to me.” It was “Brother Malcolm comes to me.” Malcolm Evans, known as Mal, was the Beatles’ road manager and one of their closest day-to-day companions.
Evans himself described the moment later: he’d been driving McCartney home at three in the morning when Paul told him about the song. “It was going to be ‘Brother Malcolm,'” Paul said, “but I’ve had to change it in case people get the wrong idea.” Both versions are real. The lyric just needed to carry more than one thing.
The C-Major Progression and Descending Bass Line
The song landed in C major, which is where it belongs. On a piano, C is the most natural key – all white keys, no sharps or flats, you can find the chords by feel in the dark. The four chords McCartney uses in the verse, C, G, Am, and F, turn up in hundreds of songs before and after this one. But he doesn’t just play them straight. He voices them as a descending bass line, the left hand walking step by step from C down through B, A, G, and landing on F, so the bass is always moving even when the chords feel static above it. That’s a technique that goes back to Baroque basso continuo writing — a bass line descending like that, slow and even, carries a particular weight. It’s easy to see how McCartney, being a natural bassist, would have understood and gravitated toward this.
There’s also a moment in the bridge and outro where a Bb chord arrives – a flat-VII in the key of C, borrowed from the Mixolydian mode. The Beatles used the same move in “Hey Jude.” It’s a chord that shows up in a lot of gospel and soul writing, and here it gives the song something hymn-like, a quality of address that’s easy to feel. McCartney has said he knew what he was doing with the double meaning of “Mother Mary”: “I called her ‘Mother Mary’ rather than ‘my mom Mary,'” he told poet Paul Muldoon on the podcast McCartney: A Life in Lyrics. “I knew enough to know, okay, we have a sort of double meaning going here.”
The recording most people know came together in January 1969 at the Get Back sessions in Apple’s Savile Row studio. McCartney played a Blüthner grand piano. Harrison was on guitar, Starr on drums. And then there was Billy Preston, who was invited to join the session by George Harrison. Preston had originally met the Beatles in Hamburg in 1962, when he was touring as organist behind Little Richard. On “Let It Be” his electric piano (a Fender Rhodes) carries the song’s most recognizable secondary melody – the gospel-soaked figure that runs under the verses and opens up fully at the break.
Why the Single and Album Versions Sound Different
What ended up on the album and what ended up on the single are two different things. George Martin produced the single version, released March 6, 1970: cleaner, more restrained, Harrison’s guitar solo measured and careful, the strings kept low. Phil Spector mixed the album version later that year and pushed everything forward – more strings, more brass, a heavier guitar solo from Harrison. McCartney never liked it, and in 2003 he released “Let It Be… Naked”, stripping out Spector’s additions to get back to something closer to what those January sessions actually sounded like. He’d waited thirty years to make the record the way he wanted it.
The single debuted at number six on the Billboard Hot 100 and eventually hit number one. It became a Number 1 single one day after McCartney publicly announced he was leaving the Beatles. The whole arc ends there, more or less: the dream in St. John’s Wood, the piano at three in the morning, the line that was almost about a road manager. Mal Evans died in 1976, shot by police in Los Angeles. McCartney has said he still misses him. All in all, it’s a pretty complex backstory to a seemingly straightforward song.
