Sure, I suppose "un-head the knee" could end up in the annals of rock history alongside "the walrus was Paul". Phish must agree since they continue to play all of those classic Sci-Fi Soldier tunes frequently to this day. Or maybe the underlying argument here is that the quality of the actual songs played should have zero impact on the rating of a performance? Music: it's only as good as the relative competence and/or adventurousness via which Phish play it.
