This world-premiere event is billed as “a night of razzle dazzle,” and that it will be, given that six Broadway and Signature performers will sing and dance to more than 35 songs from the John Kander and Fred Ebb playbook, which includes Chicago and Cabaret. Signature’s own Eric Shaeffer directs, with choreography from Karma Camp. An onstage 19-piece orchestra rounds out this celebration of both Kander & Ebb and 20 years of Signature. Through Sept. 27. In The Max at Signature Theatre, 4200 Campbell Ave., Arlington. Buy one regularly priced ticket – $60 to $65 – and get up to three additional tickets for just $20 each.
