Martin Scorsese's portrait of the late George Harrison.
Scorsese traces Harrison's life from his beginnings in Liverpool to becoming a world-famous musician, philanthropist and filmmaker, weaving together interviews with George and his closest friends, photographs and archive footage including live performances - much of it previously unseen.
The result is a rare glimpse into the mind of one of the most talented artists of his generation.
Part one looks at George's early years in The Beatles - from their first gigs in Hamburg and the beginning of Beatlemania, through to his psychedelic phase and involvement in religion and Indian music.
The programme includes contributions from Sir Paul McCartney, Ringo Starr, Yoko Ono, Eric Clapton, Sir George Martin and Phil Spector.
