BK mentions there being no real revival houses around the mid-1960s, which initially surprised me until I thought about it. By the time I was living in L.A. they were everywhere and going to them was a way of life. My gut guess is that they were reaching their peak in the early-mid 1980s which would coincide with cable and home video really taking off. But man, were those the days.
Oh wait, this can be an Ask BK: Someday, please please please raid your stash of "L.A. Neighborhood" movie listings (I think you said you have some) for sometime in the late 70s, early 80s. I'm thinking of that beautifully concise but thorough block listing in the Times, but anything would be of interest. I would treasure seeing a few samples of what we so took for granted then.
