Cabaret ZaZou's “Luminaire,” an intimate, interactive cabaret/cirque production performed inside a European spiegeltent on the 14th floor of the Cambria Hotel in downtown Chicago, is one of Chicago’s best-kept theatrical secrets. Frank Ferrante, the legendary actor and comedian who co-created the show and plays your host "Forte," discusses the origins of the piece; how one best describes this particular circus-music hall entertainment; not just playing but embodying Groucho Marx; the art of making audience “volunteers” look good; the mixed blessing of missing the glory days of vaudeville; receiving actual blessings from Groucho’s son; admiring both the truth and range of Zero Mostel; celebrating the anarchy of the Marx Brothers; drawing on one’s heritage for both comedy and truth; the ability to use all the skills in an actor's toolbag; and the power of an entire audience saying, as one, “All is forgiven.” (Length 20:27) (PICTURED: Frank Ferrante as Forte in Cabaret ZaZou's "Luminaire.")
