"Here, There and Everywhere" was written by Paul McCartney and credited to Lennon-McCartney. McCartney wrote most of it in early June 1966 while sitting by the pool at John Lennon's house in Weybridge, waiting for Lennon to wake up.
"Here, There and Everywhere" appears on the Beatles' 1966 album Revolver, where it is the fifth track, sequenced between George Harrison's "Love You To" and "Yellow Submarine."
McCartney has cited the Beach Boys' "God Only Knows" as the primary inspiration, calling it his favourite pop song of all time. He told Beach Boys biographer David Leaf in 1990 that the influence was specifically in the introduction's harmonies.
The Beatles recorded the song over three sessions at Abbey Road Studios on the 14th, 16th, and the 17th of June 1966. They taped 13 takes before settling on a satisfactory basic track, then spent much of the remaining time perfecting the layered backing vocals with McCartney, Lennon, and Harrison.
