TV stars were out in abundance for last night's 65th Annual Emmy Awards, but it was Carrie Underwood who stole the show.

The songstress performed as part of a special tribute for the 50th anniversary of both the tragic assassination of John F. Kennedy, as well as the Beatles performance on 'The Ed Sullivan Show,' which catapulted the group to stardom in 1963.

Underwood, looking stunning in a blue gown, was introduced by actor Don Cheadle. “National tragedy gave way to another event, and a dark cloud was suddenly lifted, making it okay to experience joy again," he shared. "73 million viewers underscored the immediacy of TV and the impact on our society. TV has the power to engage, inform and unite. It remembers the past, celebrates the present and anticipates our future."

The singer gave a flawless rendition of the Beatles' classic hit, 'Yesterday,' backed by a full orchestra, with pictures of the British band being shown behind her. Her performance even earned the approval of one of the founding members of the iconic group.

Chances are good the singer got a few tips while hanging out with so many actors, since she will next appear as Maria von Trapp in a live performance of 'The Sound of Music.' The show will air on Thursday, Dec. 5 on NBC.
