For me it would be

1. Around 1963. I would love to see the taping of a Dick Van Dyke Show episode but specifically the episode called "That's My Boy??". It's such an iconic episode of TDVDS but also an iconic episode in TV history in general. To be able to see that cast in action would be exhilarating. To see them all at the top of their games and having the time of their lives!!

2. The next would be June 1965. The Rat Pack comprised of Sammy Davis Jr, Frank Sinatra, and Dean Martin did a charity show in Missouri. You can find it on Youtube last time I checked but it's also on DVD. It's just so fun and chaotic. Like Frank will be singing a song and Sammy and Dean will be in the wings cracking jokes and heckling. Like you don't even see them, you can hear them talking in the background while the dude singing is trying not to crack up. And then they're all on stage together and things really get chaotic. It's just pure fun and I would give anything to be in the front row of that.
