Okay, it doesn't rise to the level of "A riddle wrapped in a mystery inside an enigma," but there are a couple of curiosities tied to this week's featured recording. "The Little Show" was a 1929 Broadway hit. Most of the score was written by Arthur Schwartz, whose birthday is being celebrated on tonight's "Big Broadcast." His "I Guess I'll Have to Change My Plan" was most likely introduced by Clifton Webb (you may remember him from "Laura"). Curiously, I can't find a single period recording of the song. For some reason, it started being recorded enthusiastically in late 1932. Maybe it was interpolated into another show, possibly shows up in a movie; perhaps Rudy Vallee or Bing Crosby began to feature it on their radio shows.
