The Voice is getting ready for its Season 14 premiere on Monday, Feb. 26th. In this promo, for five minutes coaches Blake Shelton, Adam Levine, Kelly Clarkson and Alicia Keys transport viewers to the Las Vegas strip in the 1960s as they embody the famed Rat Pack. This black and white clip takes place in a jazz club, where Shelton and Levine are sharing the stage for a spirited rendition of Frank Sinatra's "Fly Me to the Moon." They trade jokes, of course, then dive right in to portray Sinatra and Dean Martin. Backed by a live band, the two coaches show off their smooth crooning on the Sinatra hit.
