THE WAY MOVIES USED TO BE SHOWN IN THEATERS

I remember seeing a Chilly Willy cartoon and an info-short about the circus before the main feature (Yours, Mine and Ours in 1969~a "second run" showing) when I was six years old at the Brook Theatre in Bound Brook, NJ. I don't see movies in theaters anymore, but that theater is still there as a historic landmark; every year it shows a Lon Chaney film with organ accompaniment.
I got to see a couple of movies at the Radio City Music Hall, complete with live holiday shows--puppets, Rockettes and all.
