You'll notice in The Operetta, the other members of the "Wednesday Afternoon Fine Arts League" are considerably older than Lucy and Ethel and we see none of the familiar characters like Carolyn Applebee and Marion Strong. And then after that, we see those two characters and the other members are much closer to Lucy's age. I always like to think that after The Operetta, Lucy was summarily dismissed from the club, and Ethel resigned out of solidarity. Lucy and Ethel then created their own club using the exact the same name and recruited their far more age-appropriate friends to join. I've always found it weird in The Operetta how all the other members look more like they're in Fred's age-group or something, lol.
