How can the same song, interpreted in so many different ways, consistently produce the most incredible mind blowing performances?
And as fine a version as the original is, there is something in the very fabric of the song that is uniquely special, indeed, when it's actual DNA is placed in the right hands, it time and again, leads to some sort of magical alchemy.
Neil's guitar here is (as always) amazing but listen to the drumming of Steve Potts and listen to Booker T's organ, this isn't some normal shit going on, this is the song taking them all (they haven't got a choice) to another place entirely and they all know and realise that they haven't actually got a choice either and as such, they all gloriously embrace (with reverence) the opportunity that they've been given to perform this incredible song ...
Talking of Booker T Jones, I had the pleasure of seeing him live at The Band In The Wall in Manchester a few years back.
To my great surprise at one point in the gig he got up from his Hammond organ, strapped on a bass guitar, and proceed to sing Knockin' On Heaven's Door. He told the story of how him and Dylan were neighbours in Malibu in the early 70s, and one day Dylan called him up and asked him over to play on a few tracks, and he ended up playing bass on Dylan's version of the song. (Though I note that Booker T is officially credited with playing bass on several of the Pat Garrett Soundtrack songs, but not Knockin' On Heavens Door).
Anyway, here's Booker T's version of Knockin' On Heaven's Door.
