John Pyka is one of those bigger-than-life characters with music in his heart and a bad (read: good) case of dancin’ feet. Besides his notoriety as a magician, he appears in local musicals and struts his stuff with style and gusto. But also, for a decade now, he has assumed the persona of Big Daddy Cool (aka Johnny Dellarocca), a Swing Era hepcat and the main player in the supper-club floor shows that anchor Pyka’s Swingin' at the Roxy franchise. Backed by The Swing Kittens, Big Daddy sings and swings to the hit songs of the 1940s while vying for control of Chicago’s infamous Club Roxy, in an iconic revue that also features dance, magic and illusion. Radio City Music Hall Rockette Alina Williams co-stars, and appearing in the role of Mitzi LaMoore is Tonya Miller, the director of Music City Tango (who also happens to be a candidate for Tennessee’s 53rd State Congressional District). The cast also features Christopher James, Amber Boyer, Tiffany Hughes and Samantha Bogach. The score includes "It Don't Mean a Thing," "In the Mood," "Minnie The Moocher," "Mack the Knife," "Blues in the Night," "That Old Black Magic" and other familiar tunes.
