No artist works in a vacuum. Young men of their time, passionate music lovers who in their formative years had access to an unprecedented range of pop music thanks to Brian Epstein's NEMS record shop, Lennon, McCartney and Harrison listened, borrowed and reshaped quite an array of tracks, processing these borrowings into their own unmistakeable sound.

Named after their first publishing company, this CD, with accompanying booklet, sheds light on the Beatles' creative process.

Listen to these tracks and see how some of the best loved songs in pop music were formed.
