Update: Sam Moore, of Sam and Dave fame, has joined the lineup for Donald Trump's presidential inauguration, performing at the Make America Great Again! Welcome Celebration on Thursday, Jan. 19, the day before the inauguration proper. He said in a statement:

“As an American, I am honored to perform for President-elect Donald Trump. I was a participant in the civil rights movement and have seen many positive changes and advancement in my 81 years of living in this wonderful Country, but I know we must all join hands and work together with our new President. I honestly believe that if we can accomplish this, the best is yet to come. We all as Americans need to unite behind our new President and give him a chance. He needs everyone’s support to make America greater, stronger and an even better Country.”

Jennifer Holliday, meanwhile, has backed out, saying she suffered death threats following the original announcement that she would perform. "The gay community since Dreamgirls, for 35 years, has been faithfully there for me," she said on The View. "They were hurting and in pain."

Original story (1/13): After months of "hell no, I'm not performing at Donald Trump's inauguration" stories, three acts are officially set to play. Rocking the Jan. 19 "welcome celebration" will be Toby Keith (whose Trumpian album titles include White Trash with Money, Bullets in the Gun, That Don't Make Me a Bad Guy), 3 Doors Down (why not, we haven't heard "Kryptonite" in a few years), who returned in 2016 after a five-year album absence, and, possibly, Jennifer Holliday, the Tony- and Grammy-winning star of Broadway's original Dreamgirls

Holliday's publicist tells The Wrap the singer "has been asked to perform but she hasn’t officially agreed to do so yet. I’ll let you know later this afternoon for sure if she’ll be performing.”

Artists who independently rejected/reportedly declined to perform at Trump's invitation include Elton John, Andrea Bocelli, Céline DionGarth BrooksKissMobyR. Kelly and Charlotte Church.

Who else will be there, though, is actor/Angelina Jolie father Jon Voigt, who Billboard dubs "perhaps the most vocal and high-profile Hollywood backer of Trump." Here's the full lineup:
