Bill Irwin and David Shiner talk about "Old Hats", now playing at the Signature Theater. The show combines a classic vaudeville-style review with slapstick comedy and new visual effects in a production that’s been described as "one of the funniest shows of the past few years."

Performances have been extended through April 3rd at the Signature Theater (480 W 42nd St). For tickets and show information, click here.
