Barry
Barry Gibb is the last, remaining brother alive from the group. Tonight, he will appear at the Grammy Awards in honor of the Bee Gees tribute. Artists who have been reported to be participating include Little Big Town, Demi Lovato, Andra Day and Tori Kelly. Pentatonix has also been rumored to be participating, but we're not positive if they will be singing in the Bee Gees tribute. (Getty)
