The Mitchell Brothers O'Farrell theatre. It was actually in the Tenderloin, but we were all hicks from a tiny farm town on a high school club summer field trip at the time and that new disease was killing at least ten people a day by then.
I was only 16 then, saw it in a magazine or online years later.
I heard they shut it down, I may be wrong.
And I DO stand corrected, a person who would know told me...still engineering stress factors on poles.
