How a dog's bark transformed a Beatles session into a psychedelic rock classic

In short: In February 1968, the Beatles intended to film a promotional video for "Lady Madonna." Instead, they spent ten hours in the studio recording a high-energy track that would become a standout of the Yellow Submarine soundtrack, sparked by a moment of studio laughter.

Originally conceived by John Lennon under the working title "Hey Bullfrog," the song was a response to a request from United Artists to provide more music for the Yellow Submarine film. While recording at EMI Studios on 11 February 1968, Paul McCartney tried to provoke laughter from Lennon by imitating a barking dog. This spontaneous moment inspired the new title, "Hey Bulldog."

The recording process was remarkably efficient; the band completed the track in just ten takes over ten hours. The final version, which the group settled on during the tenth take, retained raw elements like shouts, screams, and the aforementioned dog barks. These were preserved by producer George Martin and engineer Geoff Emerick, who applied heavy compression to Lennon's dialogue and the animal noises.

Musically, the track is a complex blend of hard rock, psychedelic, blues, and acid rock. It features a shifting key that moves between B major, A major, and B minor, and is driven by a distinctive piano riff played in octaves. While Lennon suggested the song should have been the A-side single instead of "Lady Madonna," the idea was rejected by McCartney.

The song's legacy is cemented by critical acclaim. In 2018, Time Out ranked it as the 27th best Beatles song, while Rolling Stone placed it 81st in a 2020 list. It has also been covered by Dave Grohl and Jeff Lynne for the 56th Annual Grammy Awards in 2014.
