The Manchester performance was widely bootlegged (and mistakenly placed at the Royal Albert Hall). In a 1971 review for "Creem" magazine, critic Dave Marsh wrote, "My response is that crystallization of everything that is rock'n'roll music, at its finest, was to allow my jaw to drop, my body to move, to leap out of the chair ... It is an experience that one desires simply to share, to play over and over again for those he knows thirst for such pleasure. If I speak in an almost worshipful sense about this music, it is not because I have lost perspective, it is precisely because I have found it, within music, yes, that was made five years ago. But it is there and unignorable." When it finally saw in 1998, critic Richie Unterberger declared the record "an important document of rock history."
