Crikey, I find this story amazing. At 82-83 we are really lucky that Lee Konitz still does live gigs, never mind tour extensively, as he still does. Over the years, whether in Nth America or Europe one of the few people who I could guarantee there would be a good chance to see would be Lee - and he's always put in 100%. Glad to hear that he kept his cool.
Heck, he even appeared on that German MPS Tribute DVD I was watching the other night, enthusing about touring with Albert Mangelsdorff in the 60s and also in the 70s with Pastorius/Mouzon.
