Hey Danno,
I have seen Mark and iterations a few times, in the 1980s and 1990s. Towards the latter years, there seemed to be an urgency to the shows demonstrated by the accelerated tempo. Songs (and patterns) that originally grooved at 120BPM were not so great at the NASCAR speed of 140+BPM live. Did you find the performances to be closer to the recorded tempos?
And how (in general) do club members feel about the live versions of your favorite recorded songs?
