When it was released as a single along with "Eleanor Rigby," it hit #1 on every major British chart for four straight weeks. It's popularity spawned a movie of the same name with a remake in the works.
The song was written to be a children's song.
John Lennon and Donovan, a British singer-songwriter, also helped with the lyrics.
Though the song was completed after five takes on May 26, several sound effects were added on June 1.
Abbey Road employees John Skinner and Terry Condon helped produce water sounds by twirling chains in a tin bath.
The Beatles also helped produce sound effects. Lennon blew through a straw into a pan of water to create a bubbling sond, McCartney and Lennon talked through tin cans to make the incomprehensible sound of the captain's orders, and Ringo stepped outside of the recording room and yelled "Cut the cable! Drop the cable!", a line which was added into the song.
The song was eventually finished on June 22.
"Yellow Submarine" was released on August 5 in the UK and on August 8 in the United States.
The song won an Ivor Novello Award "for the highest certified sales of any single issued in the UK in 1966."
Two years later, in 1968, United Artists released an animated film also called Yellow Submarine. A remake is scheduled to be released by Disney and Robert Zemeckis in time for the 2012 Summer Olympics in London.
