Title: "Jolson Tonight" vs "Al Jolson, Tonight"

edit

After some cursory checking around I only found references to the show being called "Al Jolson, Tonight", in both Kansas City and New Orleans (though this is not a reliable source for info, I just found it while image searching) but perhaps there was a title change at one point during the tryouts? I can't find any of the sources referenced in the main article. @Phaeton23: you seem to know of this show, do you know about the title?
