In 1957, a boy named Paul met a boy named John. John was funny and confident, while Paul was quiet and steady, but one thing they had in common was a love and talent for songwriting.

When they were joined by George and Ringo, they formed the band whose name would soon be known across the world: The Beatles. Together, the Fab Four became the world's best-loved band, drawing huge crowds to packed-out stadiums.

But even they got nervous sometimes, and in those times they knew they could rely on each other. Through the power of friendship, The Beatles made their biggest dreams come true and still bring joy to the lives of millions.
