For the long medium close-up where he gets bombarded with tomatoes, hard cabbage, lettuce, etc. while trying to sing "The Barber of Seville," Carl 'Alfalfa' Switzer was told he would only be hit with soft tomatoes. Of course, when filming started, he found out the opposite. The anger seen on-screen is not acting; after the shot was done, Alfalfa grabbed his brother Harold Switzer and said, "C'mon, Harold; let's go kick their ass," and a fight almost broke out between cast and crew members. It is speculated that the vegetable toss (which was done by the crew members for this shot, not the kid opera attendees seen in the wide shot) was payback by the crew for having had to endure the pranks, tantrums, and other mischief Alfalfa regularly caused on the Our Gang sets.
The "ice cream sundaes" in Club Spanky were made using mashed potatoes and whipped cotton.
The aged character played by Henry Brandon is identical to the villainous "Barnaby" character that he portrayed in another Hal Roach comedy, Stan Laurel and Oliver Hardy's feature film Babes in Toyland. While his character in this film is not identified by any name on-screen, he was identified as "Barnaby" in the shooting script and is casually referred to as such.
