The past decade or so has brought revivals of West Side Story, Gypsy (twice), Anyone Can Whistle at Encores, Company, Follies at Encores and Broadway (twice), A Little Night Music, The Frogs, Pacific Overtures, Sweeney Todd (with rumors of the London production on the way), Merrily at Encores, Sunday in the Park, Into the Woods (with some expecting a transfer of this summer's Central Park production), Assassins, Passion Off-Broadway at CSC this fall, plus revues like Putting it Together and Sondheim on Sondheim and countless 80th birthday celebrations, plus the NY premieres of Saturday NIght and Road Show. I guess we are due for Forum since it was last revived in 1996. I love his work and all, but New York stages have really turned into "Stephen Sondheim, This Is Your Life".
Begin at the beginning and go on till you come to the end: then stop.
