It's time to celebrate the people who keep so many shows afloat with their work ethic, adaptability and brains full of choreography: swings! As BroadwayWorld previously reported, Actors' Equity is celebrating its fifth annual Swing Day today, January 15, honoring the hard-working performers who stay ready to go on at a moment's notice, for multiple roles. We're getting in on the celebration by highlighting some of the swings that are lighting up the stage both on Broadway and on national tours. Take a look below to see these hardworking cast members from Moulin Rouge, Hamilton, Mean Girls, and more!
