When The Beatles performed on The Ed Sullivan Show in February 1964 it was watched by an estimated 73 million US viewers and sparked the arrival of the Fab Four - and Beatlemania - in America. What followed had never been witnessed in pop music before, and perhaps never has again, as the entire world was swept up in delirious adulation of four young lads from Liverpool.

Oscar-winning director Ron Howard chronicles "the touring years", as The Beatles performed more than 1,400 times all over the world. Gaining rare interviews with Sir Paul McCartney, Ringo Starr and widows Yoko Ono Lennon and Olivia Lennon, and featuring unseen footage of the band at their peak, Eight Days A Week is the ultimate record of these musical icons.
