I was at the show. Sam was in great form despite having to take breath-catching breaks. The chemistry was there up the wazoo. Having seen that trio so many times at Rivbea from 1974-76, it was especially poignant for me. I did miss the extended percussion that Altschul had jettisoned by then, though. None of the sirens, temple blocks, cowbells, etc., as far as I remember.
