Walter Bobbie is director of a show that is set in the Chicago of Al Capone, but he sees it as an essentially modern piece, relevant to today. What he wants is an overriding image, an energy and an immediacy.

The immediacy comes largely from the writing of Kander and Ebb, who grab the audience with All That Jazz and hold it through a succession of hits that include Cell Block Tango, When You're Good to Mamma, Razzle Dazzle and Class.
