Pink Floyd – Shine on You Crazy Diamond

* For a certain lady, whom I love. *

I remember vividly the very first time that I heard this music. I was all of thirteen years young and on a school vacation in the Ardennes in Belgium. About two-hundred students were sat in a big circle in some kind of PE hall, when the music came on strong and two hippies, one young man and one young lady, both with long flowing hair and robes, started whirling around and dancing as if in a trance. It was magic then and still is now.
