Sorry, I was referring to formal music education. Such beautiful harmonies from someone whose music education was listening to 45s and pounding away on his guitar in a backroom.
To me, it's like Newton discovering gravity and calculus, or Einstein discovering the theory of relativity, but with only a background in dirt farming.
[Edit] Oops, sorry BM and AB, I didn't see you had answered already!
Agree with you, Alexis. Lennon had a streak of genius in him. And when it dawned on him the result was stupendous.
