Garth Brooks and Trisha Yearwood also represented Nashville during the 'Sinatra 100' broadcast.

Country talent Zac Brown and Carrie Underwood performed during the televised Sinatra 100 — An All-Star Grammy Concert, marking what would have been Frank Sinatra’s 100th birthday.

Carrie Underwood put her own spin on the classic “Someone to Watch Over Me” and looked like an absolute dream in a cream and black lace gown.

Zac Brown cleans up real nice and took the stage for a rendition of the feel-good romantic tune, “The Way You Look Tonight.” The Zac Brown Band frontman clearly enjoyed his time in the spotlight— check out that huge smile!

The special Sinatra 100 program aired Dec. 6th on CBS. Besides Underwood and Brown, the concert also featured country music power couple Garth Brooks and Trisha Yearwood. Check out what Trisha had to say about her early musical influences below.
