If you could go back and witness any historical event, which one would you pick?

I would love to go back to the late 1960’s to the 1970’s and witness one of Led Zeppelin’s concerts.  This is when John Bonham was with Led Zeppelin. He was an incredible drummer. RIP John Bonham. They have said, he is the best drummer to ever live. So to witness one of his concerts would be amazing. Then, Jimmy Page on guitar, Robert Plant singing and Jon Paul Jones on bass would be such a treat to witness the power of all four of them playing. It would be a great concert. Thank you for reading. Have a good night.
