"Were you the kid with the plaid pants?"
LOL! Actually plaid pants were 70's. I graduated from HS in 1963, so I was wearing the skinny black pants and white shirt, with a REALLY narrow tie.
Our church didn't do any such nonsense about dancing and the like, so I just went to the Senior Dance and had a good time.
However, I always did like the church potluck dinners. I still do. I go to them frequently at local Lutheran churches.
It works really well. I bring a nice casserole and, since I'm not a member, lots of friendly people want to talk with me. Food's good, too.
I've always gone to church potlucks. I probably always will.
