At the 11:30 PM concert, Sajous will premiere a brand-new show co-conceived with and directed by Ethan Paulini, whom she met while performing in The Who's Tommy.

"Ever since I met Saj, I knew I wanted to work with her frequently and often," Paulini said in a statement. "Over the years we have not only developed an incredible artistic relationship but she has become a friend, a member of my family. I am so thrilled to be collaborating with this remarkable talent on such a personal and fulfilling project. We are honored to be presenting this evening of song and story at such a prestigious and exciting venue and look forward to many more ventures, laughs and memories."

Sajous made her Broadway debut as Extraordinary Girl in Green Day's American Idiot. She went on to originate the role of Shirley in Baby It's You! She next appeared as Arachne in Spider-Man Turn Off the Dark, Claire in Forever Dusty and Blossom in Anna Nicole: The Opera at BAM.

Paulini created, directed and starred in the hit show Mama and Her Boy (currently in its second year Off-Broadway). Sajous is a frequent guest star in Paulini's Mama and Her Boys.
