Based on the semi-hit Broadway musical of 1968 starring Joel Grey, this TV version has been re-fashioned in significant ways. The premise here is that a small group of modern-day performers have gotten together in a rehearsal studio to celebrate George M. Cohan's life and work. Joel Grey and Bernadette Peters (also from the original cast) and the other cast members are apparently playing themselves, with Austin Pendleton serving as a stage manager/director.
