The Hamilton cast members aren't the only Broadway folk singing at the White House in Washington DC this month.
The theme of the event, the last of President Barack Obama's two terms, was “Let's Celebrate.” Menzel sang the national anthem before the event, in which invited children raced to roll the specially designed colored keepsake eggs across the White House lawn.
An estimated 35,000 people attended.
The event was streamed live at WhiteHouse.gov/live. Watch a video of Menzel's performance here:
