The Beatles were inspired and influenced by music - R&B, Rock'n'roll, Blues, etc. - bought in from the US by friends, relatives, a guy you met in a pub, who'd just come from there, Liverpool being a major seaport; notably that fine traditional musician Buddy Holly. Not first-hand English, although some English music had crossed the other way in the previous century. Most of the emigrants were Irish and Scottish, of course; not forgetting the African (and Brit too) slaves in the plantations.
