I've always liked this episode, and not just for Herb's discussion of Fantasia. One thing I like about it is that it takes a very standard story (saving a building from being demolished) with a pre-determined ending (of course they're not going to have to move) and makes it interesting by, among other things, focusing more on character relationships -- Bailey and Mr. Carlson, specifically -- than on plot. The episode doesn't even end with the building being saved; it just assumes that we know it will happen.
This was an episode The Comedy Network only had in the 22-minute syndication version, so I had to get missing scenes and music (including a snippet of "What'd I Say" by Ray Charles, a perpetual Johnny Fever favorite) from a lower-quality tape. But the whole episode is here, music and all. I can't identify all the music but the song played by the piano in the bar is "Lady Be Good" by George Gershwin.
