For me, it's the Beatle's rooftop performance on the Let It Be film. I mean, all four of 'em had great mops up there, but specifically John Lennon did it best for me. It's possibly what turned me on to growing out my hair. More than any other performance I've seen, John Lennon had hair that was *alive,* it was helping him play guitar up there, showing just as much passion as his face did. What's cool is that in a few months, my hair is probably going to be roughly the same length and style as John's was back then. If I wasn't so behind in my studies, I'd try to learn guitar just so I can try to perform like that over the Summer, even if just in my parents' livingroom.
