1. When I hear Martin Luther (the) King's "I Have A Dream" speech. I think this one is pretty self-explanatory. This has to be one of the most beautiful speeches ever, both in content and delivery. I have a CD by this group "Moodswings" that incorporates the speech into one of their tracks. It gets me every time.
2. The part in the Paul Simon song "Obvious Child", when the drums end and Paul stars singing "Oooooo, oo-oo-oo-ooooo. Oo-oo-oo-oooo..." Something about it. It's so pretty.
3. The final scene in "Star Wars: A New Hope", when the music kicks in. Leia is there, looking fly in her princess garb. The three heroes make the long walk in. The feeling of triumph. I love it.
