The Zac Brown Band has been added to the list of performers who will celebrate the legacy of Frank Sinatra on "Sinatra 100 – An All-Star Grammy Concert."

The event, which tapes at the Encore Theatre at Wynn Las Vegas on Dec. 2 and airs at 9 p.m. Dec. 6 on CBS, will also feature another prominent Atlantan – Usher – as well as Celine Dion, Lady Gaga, Harry Connick Jr., Tony Bennett, Alicia Keys, Garth Brooks, John Legend, Adam Levine and Carrie Underwood.

The live concert will spotlight the artists performing Sinatra songs in honor of what would have been his 100th birthday (on Dec. 12). The iconic crooner died in 1998 at the age of 82.

It's another high-profile appearance for ZBB, which is in the final weeks of its "Jekyll + Hyde" tour. The outing launched in May – the guys performed a two-night stand in Alpharetta early in the tour – and by the time it wraps next month, ZBB will have traveled more than 38,000 miles in an envoy of eight buses and 16 trucks.

The band didn’t have much luck at the CMA Awards last week, losing Vocal Group of the Year to Little Big Town, but their excellent “Jekyll + Hyde” album will surely get some notice when Grammy nominations are announced Dec. 7.

Check out the band's performance of "Beautiful Drug" from the CMA Awards.
