"I'd given them all beans and toast this evening. It was several months before John's mother died and he was just getting really close to her. I overheard him say to Paul, "I don't know how you can sit there and act normal with your mother dead. If anything like that happened to me, I'd go off me head." When John's mother did die, he didn't appear to go off his head, but he wouldn't come out. I forced George to go round and see him, to make sure he still went off playing in their group and just didn't sit at home and brood. They all went through a lot together, even in those early days, and they always helped each other. George was terrified that I was going to die next. He'd watch me carefully all the time. I told him not to be so silly. I wasn't going to die."
