You get a sense, throughout, that this is a nomadic band: the McCartneys’ young children, Mary and Stella, travelled with them in a sheared-off double decker bus painted psychedelic colours, which caused controversy at the time. “We always imagined that, if we didn’t take the kids, we would end up in some far-flung place,” McCartney tells me, “and somebody would be ringing from England and saying, ‘One of the kids is ill’, and we’d think, ‘Oh, God, we should be there… We should be there with them.’ So, we decided to take them.”
