Donald Trump will be sworn in for a second term as president Monday—with every living former president, billionaires like Elon Musk and Mark Zuckerberg, Carrie Underwood, the Village People and several foreign leaders getting invitations.

Bill Clinton, George W. Bush, Barack Obama and Joe Biden—are expected to attend the inauguration, and many more political figures will be at Monday’s ceremony. While it is unclear exactly who will be at the intimate indoor ceremony under the Capitol’s central dome,

Trump has enlisted the help of celebrity acts for the ceremony—and there will also be some famous faces in the audience.

Country singer Parker McCollum will perform at the Commander-in-Chief Ball on Monday, one of three events where the newly sworn-in president will speak.
