Today is the first official Global Beatles Day, a date finally recognised by The Beatles and Apple Corps Ltd.

On 25 June 1967, John Lennon, Paul McCartney, George Harrison and Ringo Starr walked into Studio One at London’s Abbey Road Studios and performed the first international satellite television broadcast of their beloved song ‘All You Need Is Love’.

To celebrate this official first, Euronews Culture is focusing on one of the most enduring mysteries surrounding the Fab Four, an enigma that keeps many a music lover awake at night: Who was the walrus in their classic 1967 song ‘I Am The Walrus’?

Before the truth is revealed, a bit of background first...

Written by Lennon, the song was partly inspired by Lewis Carroll's 1871 poem "The Walrus and the Carpenter", as well as two rumoured LSD trips. Lennon later expressed dismay upon belatedly realising that the walrus was the villain of the poem.
