Check out the isolated vocal tracks from "the medley" from The Beatles' Abbey Road. While there is a small amount of instrumentation, this offers an amazing look into the vocals on the record. Despite the band's impending break-up, they are able to blend together perfectly.

Eric Alper had the following to say about these recordings in Open Culture:

That medley is such an impressive demonstration of The Beatles' range of voice and sensibility that it almost functions as a capsule for the sound of their whole later career—all the weird narratives, blues, ballads, and gorgeously lush hymns and lullabies. What remains constant throughout every Beatles' record—even before George and Ringo's songwriting contributions—is the vocal and lyrical interplay of Lennon/McCartney, and it’s all on fine display in the medley.

"The medley" contains the songs "You Never Give Me Your Money" (McCartney), "Sun King" (Lennon, with McCartney and Harrison), "Mean Mr. Mustard" (Lennon), "Polythene Pam" (Lennon), "She Came In Through the Bathroom Window" (McCartney), "Golden Slumbers" (McCartney), "Carry That Weight" (McCartney, Lennon, Harrison, and Starr), and "The End" (McCartney).

Although Abbey Road wasn't the final album released by The Beatles, it was their final recording session, taking place between April and October of 1969 after the disasterous Get Back sessions. These sessions were relatively free from the conflict that had plagued the band following the death of The Beatles' manager Brian Epstein in 1967.

The album was divided into two halves as a compromise between John Lennon, who wanted to record a traditional album with individual, unrelated songs, and Paul McCartney and long-time Beatle producer George Martin, who sought to continue with a thematic approach similar to Sgt. Pepper's Lonely Hearts Club Band. "The Abbey Road Medley" is taken from McCartney and Martin's thematic portion of the album.

While initial reviews were mixed, critizing it for have an artificial and inauthentic sound, in retrospect many critics have sited Abbey Road The Beatle's greatest album.

The Abbey Road cover, featuring the band at a zebra crossing, has become one of the most famous and imitated album covers history. It's also the only Beatle cover to feature neither the band's name nor the album title.
