I predict it will be Hudson Loverro, who abruptly left the Broadway company of "A Bronx Tale" last week with no future plans announced, and who has a history with "A Christmas Story", having played younger brother Randy in last year's Papermill Playhouse production.
And this video of him singing his big number from "A Bronx Tale" in Bryant Park just a few days before he left the show will defeat the argument that he left because he outgrew the part.
