Sometimes people get cought up in what something is supposed to mean. The song I know is done by Traffic. The medly is very beautiful. I have seen Traffic preform this song a few times and I am still spellbound by it. Trying to define something that sounds beautiful can turn you off to something very wonderful. Drink a good beer and smoke a joint and kick back. It really is a good song. For those of you that can't drink well then don't.
