George Harrison’s struggle to balance a simple existence with a rock star’s hedonistic lifestyle is chronicled in the Beatles deep cut “It’s All Too Much.”

John Lennon turned a satirical pen on himself and his bandmates for this stand-out deep cut from the Beatles’ self-titled 1968 studio project.

“Your Mother Should Know” may not break new musical ground, but it further exemplifies how the Beatles drew from seemingly unlikely sources in their compositions.

The Beatles’ darkly experimental “Long, Long, Long” foreshadows a frequent trope in George Harrison’s solo work: comparing spiritual and romantic love.

Like the Beatles’ other covers, Larry Williams’ “Bad Boy” reveals their roots: In this case, rhythm and blues.

“Act Naturally” came, well, naturally for Ringo Starr. He had flirted with country music long before joining the Beatles.

The Beatles, particularly John Lennon and Paul McCartney, were avid students of the Texas-born singer-songwriter Buddy Holly.

“Anna (Go to Him)” impacted the Beatles’ songwriting, and Arthur Alexander’s heartfelt vocal style influenced John Lennon’s intensely personal performances.

The Beatles’ “Two of Us” was meant to celebrate Paul McCartney’s new romance with Linda Eastman, but it also summarized his partnership with John Lennon.

Arguably one of the Beatles’ best B-sides, “Yes It Is” features sophisticated wordplay, deeply reflective lyrics, and unusual chord changes.
