....Also, I seriously doubt I'll ever be able to listen to Paul's beautiful "For No One" again. Just too painful...
I share similar feelings about For No One. It's still part of my guitar repertoire however.
Teenage feelings are strong. My very first girlfriend said the fateful words "I just want to be friends" to me in late 1967 about a year after the song was released. For No One quickly became the musical backdrop for that event. We stayed friends for years after that but it was often difficult for me to ignore some very strong feelings I had for her.
Several years later, I taught her some blues pieces I had learned from my teacher. Suddenly she said "Teach me a Beatles song." I played For No One for her. When I finished, she said "That was nice. Show me how you play it."
So I said "It's in the key of C. Finger the C chord like this, then pluck on the fifth string and strum down on..."
