The Broadway revival of Cabaret, starring Michelle Williams, opens April 24 at Studio 54. The production features Alan Cumming, reprising his iconic 1998 Tony Award-winning performance in the lead role of the Emcee. But Cumming isn't the musical's only famed master of ceremonies — the part has been played by several of musical theater's living legends, including the role's originator, Joel Grey. This playfully naughty supercut also features a provocative Norbert Leo Butz, British Pop Idol Will Young, and a delightful surprise performer.
