Yeah, it was a gem of a night. Such a civilised event; Lewis was literally inches away from me and I could have leant on the piano. I think he really enjoyed playing to those of us (not many) in proximity. I think it was Summer 1990, so slightly before that NY recording.
At the same venue I remember seeing Jay McShann, Sir Charles Thompson, Joanne Brackeen, Cedar Walton. Just missed Stanley Cowell in solo recital though.
