The annual Inner Cirle dinner and performance raises money for dozens of causes, such as the Coalition for the Homeless, the Museum of the City of New York and the American Heart Association. In addition to the cast of Hair, Nicole Polizzi ("Snookie") and Mike Sorrentino ("The Situation") from MTV's Jersey Shore also made guest appearances.
At past Inner Circle dinners, Mayor Bloomberg has performed with the casts of The Little Mermaid, Mary Poppins and Spamalot.
