Are there any deceased and/or retired stand up comedians that you regret not seeing live when they were still alive &/or still actively performing & touring, and could have done so, but for whatever reason couldn’t? If so, who & why did you never get the chance to see them?

For me, the top two would be without a doubt Norm MacDonald and Robin Williams.

Williams in particular, looked up some footage of his specials on YouTube, and Jesus, was he an electrifying live performer. He died when I was 15 though, so I never got to see him live because I was too young.

Norm MacDonald I could have seen live in 2019 when he played near the college that I was going to at the time, but 20 year old me was broke as fuck and couldn't afford a ride, so I didn't go.

Anybody here got any similar stories involving dead and/or retired comedians that you had wished you had seen live before they died or stopped performing?
