"Willkommen" to 30 Rock! Tony winner Alan Cumming and the cast of Cabaret took to the stage of The Tonight Show and while Jimmy Fallon may be the host, there was another Master of Ceremonies heating things up on set. Cumming and the cast performed the show’s opening number, “Willkommen," affirming that, yes, one can wear suspenders (and basically nothing else) on network television. The revival, set to open on April 24, marks the first Broadway production to perform on Fallon’s The Tonight Show, though audiences can expect plenty more musical appearances in the near future. Take a look at the performance below and then get the full Kit Kat Klub experience in person at Cabaret, now in previews at Studio 54! Oh, and thanks for the Broadway.com shoutout as you introduced the guest lineup, Mr. Fallon!
