Sakolove steps into the production as a swing, while Mosher, who starred in Hairspray on Broadway, replaces Christine Pedi, who is currently playing a 10-week engagement in Broadway's Chicago.

"I'm so thrilled Susie is back,” said producer Tom D’Angora in a statement. “She is one of the funniest people in North America and we have missed her…I've been waiting a long time to work with Carly and the timing finally lined up. Her talents are a perfect fit for our quirky little show."

Sakolove is best known for her Youtube video "Broadway Divas Send in the Clowns," a parody where she displays her range of vocal talents, portraying Bernadette Peters, Patti LuPone and Liza Minnelli.

The company currently features Michael West, Tommy Walker, Christina Bianco and Ryan Knowles.
