Leia o trecho seguinte, do livro The Love You Make, An Insider’s Story of The Beatles, de P. Brown e S. Gaines (trecho em que são mencionados John Lennon, sua mãe Julia, sua tia Mimi e seu pai Fred e responda à questão.

(...) But by that summer it had become clear that John wasn’t interested in his education, or in art, or in his future at all. John’s only interest was the American craze called “rock and roll”, a derivative form of black rhythm and blues with a prominent drum beat. (...)

John wanted a guitar more than he had wanted anything before in his life. Surprisingly, it wasn’t Julia who broke down and bought it for him, it was Mimi who marched him to a music shop in Whitechapel and bought him his first guitar for £17. A small, Spanish model with cheap wire strings, he played it continuously until his fingers bled. Julia taught him some banjo chords she had learned from Fred, and he started with those. He sat on the bed all day, and when Mimi tried to shoo him into the sunlight, he’d go out to the support and lean up against the brick wall practicing his guitar for so long that Mimi thought he’d rub part of the brick away with his behind. She watched him waste hour after hour, day after day with the damned thing and regretted having bought it for him. “The guitar’s all very well, John,” she warned him, “but you’ll never make a living out of it.”
