I was listening to Radio Paradise today and the Grateful Dead song "Ripple" came on. I hadn't heard that tune for awhile and it reminded me of how good the Grateful Dead were (are).
There's a Real Audio file of the Grateful Dead Song Ripple at the top of this page.
I like the tune and the general "feel" of the lyrics. If you into analyzing lyrics and want a detailed discussion you could check out The Annotated "Ripple".
