Should the Mormon Tabernacle Choir Sing at Trump's Inauguration?

Having heard that a member of the Mormon Tabernacle Choir has resigned
because as she says, "it will appear that Choir is endorsing tyranny and
fascism by singing for this man", I thought I would look at this situation.
Here is the official statement by the Choir leader:

“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."

Members of the 360-member volunteer choir will travel to the nation’s capital

for the historic event."

To me the position of the Mormon Tabernacle Choir is that they desire to serve our country and uphold our government, not endorse a specific President. The facts support this conclusion. The articles I read gave a list of performances the Choir has given for different US Presidents.
