The word "legend" gets used a lot when referring to actors, singers, athletes and the like. But this is an event that demands we use that term. Because not only is there a true legend of show business appearing at this show, there are two of them. Carol Channing and Tommy Tune, two of the most talented and celebrated artists in the history of Broadway theater, will join together on one stage to share their stories and memories of a lifetime in entertainment. Time Steppin', which does not include performances, features a talk between the two show-business veterans, who have known each other for decades.
