In 1969, Spector made a brief return to the music business by signing a production deal with
A&M Records. A Ronettes single, "You Came, You Saw, You Conquered" flopped, but Spector returned to the Hot 100 with "Black Pearl", by Sonny Charles and the Checkmates, Ltd. Although the record reached #13, the
In 1970,
Allen Klein, manager of
The Beatles, brought Spector to England. While producing
John Lennon's hit solo single "
Instant Karma!", which went to #3, Spector was invited by Lennon and
George Harrison to take on the task of turning the Beatles abandoned "
Get Back" recording sessions into a usable album. Spector went to work using many of his production techniques, making significant changes to the arrangements and sound of some songs. The resulting album,
Let It Be, was a massive commercial success and topped the US and UK charts. The album also yielded the #1 single, "
The Long and Winding Road". Although viewed as a major creative comeback for Spector, it may also have contributed to the contentious Beatles breakup, as Spector added what some considered inappropriate choir and orchestral arrangements to Lennon's "
Across the Universe", and Harrison's "
I Me Mine". His overdubbing of "The Long and Winding Road" infuriated its composer,
Paul McCartney, especially since the work was allegedly completed without his knowledge and without any opportunity for him to assess the results. In 2003, McCartney spearheaded the release of
Let It Be... Naked, which stripped the songs of Spector's input.
However, both John Lennon and
George Harrison were satisfied with the results, and
Let It Be led to Spector co-producing albums with both ex-Beatles. For George Harrison's multi-platinum album
All Things Must Pass (#1, 1970), Spector provided a cathedral-like sonic ambiance, complete with ornate orchestrations and gospel-like choirs. The LP yielded two major hits: "
My Sweet Lord" (#1) and "
What Is Life" (#10). That same year, Spector co-produced John Lennon's
Plastic Ono Band (#6) album, which featured a very different, sparse and raw sound.
In 1971, Spector was named director of A&R for
Apple Records. He only held the post for a year, but during that time he co-produced the single "
Power to the People" with John Lennon (#11), as well as Lennon's chart-topping
Imagine album, including the #3 title track. With George Harrison, Spector co-produced Harrison's "
Bangla-Desh" (a #23 hit), wife Ronnie Spector's "
Try Some, Buy Some" (which made it to #77), and the music for the #1 triple album
The Concert For Bangla Desh.
Lennon retained Spector for the 1971
Christmas single "
Happy Xmas (War Is Over)," the poorly-reviewed 1972 album
Some Time In New York City (#48), and the 1973 sessions for the album,
Rock 'n' Roll (#6). Spector's relationship with Lennon ended during these sessions; some versions claim that the producer suffered a breakdown in the studio, brandishing a gun and disappearing with the
Rock 'n' Roll tapes, although Spector biographer Dave Thompson places most of the blame on the out-of-control behavior of Lennon and his entourage. After several months, Lennon retrieved the tapes and finished the album himself.
