I took a look at a historical photo book about Fullerton California, in Arcadia Publishing's "Postcard Series."
The caption writers pointed out several errors on old photos, such as misidentification or misspelling of street names. But the photo of the Fox Theater (I can't remember if it had BECOME the Fox yet) shows a banner promoting "Buck Benny Rides Again." The caption points out that the movie starred "comedienne Jack Benny."
I guess somebody found "Charlie's Aunt" convincing...
