Lincoln Center Theater kicks off its 20th anniversary season with The Frogs, based on a comedy written in 405 B.C. by Aristophanes, freely adapted by Burt Shevelove, and even more freely adapted by Nathan Lane. The show features music and lyrics by Stephen Sondheim and direction and choreography by Susan Stroman. The cast of 27 features John Byner, Peter Bartlett, Daniel Davis, Roger Bart, Nathan Lane, Burke Moses, Michael Siberry. The Greek god Dionysos (to be played by Nathan Lane), troubled by the world's ills, embarks on a perilous and frog-infested journey to Hades with his slave Xanthias, to bring back an extraordinary writer who, by providing words of wit and wisdom, will help save mankind from self-destruction.
