I was trying to look up some information on Dark Star and came across a published essay about the version on Live/Dead. Bloody fascinating read. I then looked up the version on YouTube and I could see the interplay the author was describing. Something to the effect of Phil and Bob trying to get off of the intro sequence and Jerry refusing to play an F# instead of F (iirc... it was years ago). After Phil makes a few pushy attempts Jerry relents and they move on. It forced me to rethink and appreciate the Dead more than I had previously. Younger me never quite 'got' the musicianship and the ethic of the band.
