I actually saw the Brubeck quartet around that time (I was 12 in 1959). It was a concert venue in an amusement park near Salt Lake City (my family, from central Illinois, were visiting my father's siblings who lived in Utah). This was the biggest thrill of my life until that point - I was totally hooked on Brubeck - not any other jazz, but exclusively Brubeck.
Joe Morello at one point slightly misaimed a snare hit in the middle of a frenetic solo and the drumstick when flying up and across the stage. He literally did not miss a beat but had another in hand so quickly you'd never know it happened without the visual experience.
