A space boy dream-the puppet show.

In the distant future, the year 2000, I put on a puppet show of a space boy dream at my high school. I got permission from jeepster (that’s who it was at the time right?) but I’m looking to revive the vignette and re-stage it. But I’m not sure how to go about making sure I’m in the clear 25 years later. Anybody have any suggestions? Thanks in advance.
