According to Paul's brother Mike, McCartney's father was also disapproving, declaring that Lennon would get his son "into trouble", although he later allowed the fledgling band to rehearse in the McCartneys' front room at 20 Forthlin Road.
Segundo Mike, o irmán de Paul, o pai deles tampouco aprobaba as relacións de Paul, dicindo que Lennon o ía meter "en problemas", aínda que despois permitiría ensaiar á novel banda na sala da casa familiar dos McCartney no 20 de Forthlin Road.
