Elvis Presley is being honored with an all-star night of performances to commemorate his iconic 1968 TV special, and the big acts that showed up were definitely worthy of paying tribute to The King.

"The 50th Anniversary of the Elvis Comeback Special" taped this week on the Universal lot in Los Angeles on the same stage used for NBC's "The Voice." The production was so big, it took two days to film in front of a live audience.

Elvis' daughter and granddaughter, Lisa Marie Presley and Riley Keough, shared in some of the hosting duties for the remake of his famous 1968 Comeback special. On December 3, 1968, Elvis performed live on NBC for the first time since 1961, and it ended up becoming NBC's highest-rated show of the season.

Sources at the taping tell The Blast the lineup was absolutely insane and featured the hottest entertainers around performing Elvis' greatest hits.

We're told the first night included Blake Shelton, Post Malone, Keith Urban, Shawn Mendes, Little Big Town, Mac Davis and Darius Rucker.

Interestingly enough, we're told Miranda Lambert actually performed during the second night of filming with her group, Pistol Annies, which also includes Ashley Monroe and Angaleena Presley (no relation).

Sources at the show tell us Lambert seemed noticeably irritated throughout her performance and "walked offstage" as soon as the music was over. We're told the audience members were speculating her sour mood was perhaps brought on by performing on "The Voice" stage, considering the history with Blake Shelton.

The second night also brought performances from Adam Lambert, John Fogerty and Dierks Bentley. We're told it was an amazing night and the crowd was definitely left all shook up.

Along with the live performances, the tapings also included pre-recorded songs from Jennifer Lopez, Carrie Underwood, Ed Sheeran, Alessia Cara, Yolanda Adams and John Legend.

The special — which will also include rare Elvis footage, outtakes and interviews — will air in 2019.
