Outside, It Is So Hot! Watch Alan Cumming & The Cast of Cabaret Heat Up Rockefeller Plaza

Willkommen to 30 Rock! Alan Cumming and his Cabaret costars recently brought some naughtiness to The Today Show. The tuner was originally supposed to perform on the 30 Rock plaza in May as part of the Today’s “Best of Broadway” series, but unfortunately canceled their appearance due to weather. With the rain clouds gone, Cumming and the Kit Kat Klub boys and girls grabbed their instruments and performed the Kander and Ebb tuner’s steamy opener, “Willkommen." Watch the clip of their performance below then check out Cabaret for yourself at Studio 54!
