I had an opportunity to hear him live, almost 18 years ago, in my hometown. Funny thing was that the concert started hour after midnight, because there was another performer, before, on the same stage, in towns theatre. So, untill one concert started, finished, and the time that was needed to set up another performance, the time ran away, which was fine for everybody.
Remember that he joked that after the concert he has a flight to catch and that he will go directly to airport, because the audience kept him on stage with constant demands for more encore.
Found some old link with program
http://mariomendes.tripod.com/Could not find the link with actual performance, aldo the national tv recorded it, but here is the link with concert of Joe Zawinul Syndicate from next year.
The quality is not the best, the music is fusion, but it can show glims of
atmosphere and interview with Zawinull himself (around 5:50) if someone is interested.
