I remembering reading, a long, long time ago, while the series was original airing, that on a very rare blue moon, a few select fans were permitted to watch during a taping; maybe not the whole episode, but at least part of one, if they swore absolute silence (during and after taping). So, I guess in a way, there was an occasional "live studio audience."
But now I'm trying to envision a live studio audience. Would there be an "uh-oh" lady, as in the audience during the taping of I Love Lucy? Actually, the "uh-oh" lady was noneother than Lucille Ball's own mother, who attended quite a few of the tapings. A recording of it was kept by CBS studios for other sit-coms that had canned laugh-tracks, including The Munsters and Gilligan's Island.
I'm surprised that on various musical/comedy/variety shows at that time that there never were any spoofs of DS. The Carol Burnett Show could've done a great one, with Ms. Burnett playing maybe Julia or even Elizabeth (or both). Of course, her show was all done before a live studio audience, bloopers and all. Oh, god, the bloopers that the network aired because they were so hysterical! Remember the horse peeing? And Tim Conway starting to ad-lib about the Siamese elephants during a Eunice and Mama skit and they just kept the cameras rolling and aired it in its entirety (except bleeping out one word that Vicki Lawrence said during it who refused to crack up and was determined to make Tim Conway crack up and succeeded)? What would an audience do during DS bloopers? Like the window pane falling down when Charity/Pansey waltzed into Tate's studio? Adam and David knocking over bushes with Christmas-tree-bases? Stuck doors? Entire "brick walls" ready to collapse?
