I now regret that I passed up the opportunity of seeing the MJQ. When I was young they, together with the Brubeck quartet, had a massive appeal to people who didn't like Bird, Diz, Bud and Monk, so for for me they weren't cool. As for the Brubeck quartet with Desmond, they came here so often, I just couldn't avoid them and ended up seeing them three times in three different cities!
Fortunately, the Ellington band came just as often and I was there every time!
