I saw it 3 times with that original cast. It was creepy as hell, but Heckart was amazing. The audience didn't take kindly to Regina Baff's flopping boobies at the end, knowing Kipp Osbourne was about to schtup her dead body. I'd love to see Keen Company (or Second Stage) do a revival, but it will probably never happen while Ira Levin's son the dentist controls the rights.
