Taped in February, this star-studded salute to the music of the Bee Gees is attended by the last surviving group member, Barry Gibb, and its executive producer is long-time Grammy Awards showman Ken Ehrlich. That means this lineup will feature not just ratings-bait nostalgia, but inspired pairings of artists and material. Celine Dion sings “Immortality,” not a Bee Gees song at all, but a song the Gibb brothers wrote for her in 1997. Old, pre-disco Bee Gees compositions also are represented: the performers and performances on this CBS special include Keith Urban doing “To Love Somebody,” Ed Sheeran performing “Massachusetts,” the appropriately named Panic! at the Disco doing “Lonely Days,” and – listen to this – John Legend and Stevie Wonder teaming on “How Can You Mend a Broken Heart.” In other words, even disco haters will enjoy this special. And for those among you who love the mirror-globe falsetto stuff, that’s here too. And so is Barry, taking the lead for the big finale.
