Once I saw that group as a quartet (Tyner, Bartz, Lee, Fletcher) without John Blake at a short-lived jazz club in Oak Cliff called the Judge's Chambers--they played a version of Contemplation that was sublime.
Was he in ill health at the time?
He certainly didn't suck any of the times I saw him.
The last time was around 1998 at the Village Vanguard--sitting in the front row, with his vibes and marimba directly in front of me, that was amazing.
The first time was at Lush Life in the early 1980s--the club was almost empty and I got to talk with him awhile; he was very friendly.
Also at the Caravan of Dreams circa mid-1980s, and then as well with the Timeless All Stars at the New Orleans Jazz and Heritage Festival. All were good.
