I remember seeing it in San Lorenzo, CA, opening weekend '71. The old Lorenzo Theater was packed. Went with a couple of buds, back when you could bring your own snacks (Fritos and Space Food Sticks!).
When the curtains parted and "Metro Goldwyn Mayer presents A Dan Curtis Production" appeared. The first notes of the theme song played, a raucous mix of applause and cheers rang out! Two hours later we saw Barnabas get his just desserts.

I saw the first segment Maybe it's just old age, The guys seemed so shallow and sarcastic! The City was as beautiful as ever. Just made me happy to be OUT of the dating game.
