GRAMMY-winning artists Zac Brown, Harry Connick Jr., Celine Dion, and Lady Gaga have been added to the performance lineup for "Sinatra 100 — An All-Star GRAMMY Concert," a primetime entertainment special honoring the legacy of Frank Sinatra. Previously announced performers are GRAMMY winners Tony Bennett, Garth Brooks, Alicia Keys, John Legend, Adam Levine, Carrie Underwood, and Usher.

The special will celebrate the late Sinatra's 100th birthday with a stellar lineup of entertainers performing songs made famous by the "Chairman of the Board." The live concert taping will be held on Dec. 2 at Wynn Las Vegas' Encore Theatre. The special will be broadcast on the CBS Television Network on Sunday, Dec. 6 from 9–11 p.m. ET/PT.   

"Frank Sinatra was a mentor, colleague and dear friend of mine and he was the master of intimate singing," said Bennett.

"I've been singing Frank Sinatra songs in my shows for many years," said Dion. "His voice has been such an inspiration for me and it will always be."

"My grandfather introduced me to Frank Sinatra," said Keys. "I love hearing his songs, the phrasing, the innocence — the subtle depth that knocks you out when you concentrate on the lyrics. And those arrangements! It brings me back to the lost art of 'the gentleman.'"

"Nobody could juggle a drink, a conversation and a perfect vocal as casually as Frank," said Levine. "That's why I love him."

In partnership with the Sinatra family, "Sinatra 100 — An All-Star GRAMMY Concert" is produced by AEG Ehrlich Ventures, LLC. Ken Ehrlich is the executive producer, Lou Horvitz is director, and David Wild and Ehrlich are writers.
