I went to see Rocky Horror with some friends in San Jose as a kid in high school in 1979. Hilarious both on-screen and off, with people throwing toast and rice at the screen.
Didn’t people throw toilet paper rolls too?
That was the fun.
I remember in Florida, when we watched, the best line the audience would shout out was, “FSU! FSU! Where the girls are girls and the guys are too!”
