Among those scheduled to perform are Mamma Mia!'s Sara Kramer, The 25th Annual Putnam County Spelling Bee's Kate Wetherhead, Little Women's Julie Foldesi and Jersey Boys' Michael Longoria as well as Ellyn Marsh and Charly Seamon. Ragtime and Dessa Rose composer Stephen Flaherty will also be part of the evening. The 7 concert will feature musical direction by Barbara Anselmi.
