If your in Australia, on Channel 9now, season 1 and 2 are streaming. “Jamie and the king”, episode 19, season 2 is entirely filmed at Dave’s house. It was filmed late ‘76 and aired early ‘77. As cheesy as the show is, it’s damn good. The books on the shelves look to be untouched in the library scene. A lot of the exterior and interior are seen, the famous staircase is seen. It’s worth a look.
