May not be the exact date. Year is correct. Things were a bit fuzzy back in those days.

I was there; worked for KGB assembling the sky show; set up scaffold, hung a sail from the light bar above the scoreboard for a screen to shoot laser on. Backstage pass; sat on the stage with Chuck Berry and his daughter as they performed. Worked at least 24 hours straight to get all the effects, light boxes, etc. set up. Helped the Zambellis set up a firework tribute to John Lennon; four mortars; had to be in a perfect square; each mortar at a specific degree; when they were set off, there was a solid light from each corner, and all four met in the middle far above the stadium. Celebrated with them; they shared some whiskey; we shared some "other stuff".....
