Ko te pānuitanga tuatahi o te rōpū ko Elvis Presley, Carl Perkins, Little Richard me Chuck Berry. I te wā o te noho tahi o te rōpū ki Little Richard i te Star-Club i Hamburg, mai i te Paenga-whāwhā ki te Mei 1962, i tohutohu ia ki a rātau i runga i te tikanga tika mō te whakatangitangi i ana waiata. E pā ana ki a Presley, ka mea a Lennon, "Kahore he mea i pā ki ahau kia rongo ra ano ahau i a Elvis. Ki te kore i reira Elvis, kāore i reira te Beatles".Ko ētahi atu pānuitanga o mua ko Buddy Holly, Eddie Cochran, Roy Orbison me te Everly Brothers. I haere tonu te rōpū ki te tango i ngā pānuitanga i muri i to ratou angitu tuatahi, i te nuinga o te wā i kitea e rātau ngā huarahi waiata me ngā kupu waiata mā te whakarongo ki o rātau hoa noho, tae atu ki a Bob Dylan, te Who, Frank Zappa, te Lovin' Byron, te Spoon, me te Beach Boys, ko tana pukaemi o te tau 1966, i miharo ki a Petney Boys, i whakaawe hoki
