The Mormon Tabernacle Choir has posted this:
At the request of the U. S. Presidential Inauguration Committee, the Mormon Tabernacle Choir has accepted an invitation to sing at the swearing-in ceremony during the presidential inauguration at the U.S. Capitol next month in Washington, D.C.
On January 20, 2017, the Choir will perform during the inauguration ceremony for President-elect Donald J. Trump and Vice President-elect Michael R. Pence.
This performance will mark the sixth time the Mormon Tabernacle Choir has sung at an inauguration. These inaugural events include the official swearing-in ceremonies for George H. W. Bush (1989), Richard M. Nixon (1969), and Lyndon B. Johnson (1965). They performed in inaugural parades for George W. Bush (2001), George H. W. Bush (1989), and Ronald W. Reagan (1981).
“The Mormon Tabernacle Choir has a great tradition of performing at the inaugurals of U. S. presidents,” said Ron Jarrett, president of the Mormon Tabernacle Choir. “Singing the music of America is one of the things we do best. We are honored to be able to serve our country by providing music for the inauguration of our next president.”
