What happened?

I remember my childhood like it was yesterday. I remember the music my older brother brought home. I would wonder what is rock n roll? Is this something important? Doesn't sound like neapolitan folk songs my parents played on the stereo record player? The singers sing songs that have words in english and they use electrical instruments. There were three albums my brother brought home he had borrowed from his friends that I would listen to secretly when he was in school, my parents were off to work, and I was home alone. Those were Sticky Fingers, Blonde on Blonde, and Let it Be.  I had favorites on these albums I would listen to repetitively. No doubt I must have listened to Dead Flowers, Just Like a Woman, and Two of Us a thousand times each. That's why I cringe sometimes when I hear them again. Listening to Dylan led me to read about Dylan and his folk roots and his crossing over to the electric guitar etc etc. Led me to study folk music from Leadbelly to Woody
