No real purpose behind it, but it is still very pretty. And the accompaniment is equally gorgeous. Very gentle, mellifluous, serene groove. Trey lets loose a few digital delay loops. They just kick things down a level, so to speak, and groove without screaming and thundering.
Page plays around on the clavinet.
But the lyrics don't come in. They jam a bit more. Page alternates between the piano, the organ and the clavinet. Fish is still keeping the rhythm, but very quietly. I imagine there was another minute or so left in this version.
