In this comedy about a wedding, It Shoulda Been You, the “you” is a young man, the former boyfriend of the bride-to-be, played with gusto by Josh Grisetti in his Broadway debut at the Brooks Atkinson Theater. His Marty Kaufman is Jewish, so of course he’s perfect for the bride, who has instead chosen a goy (David Burtka) who insists upon learning Yiddish. I’ve had a crush on Josh Grisetti ever since I died laughing watching him in Enter Laughing at Sag Harbor’s Bay Street Theater a few seasons ago. The show went on to a run Off Broadway. Now Grisetti gets to display the full force of his talents in a show of eminent performers including Tyne Daly as mother of the bride, and Harriet Harris as mother of the groom, who go head to head, curlered to coiffed. Directed by David Hyde Pierce, this farce including the genre’s traditional slamming doors, is a shtick fest with a twist.
