Some people say there are no coincidences. If that’s true, how in the hell do you explain the fact that Wednesday’s late-night TV musical performances consisted of not one but two different a cappella performances? First up, you had the legendary David Crosby offering his confrontational classic What Are Their Names — which originally appeared on his 1971 solo debut If I Could Only Remember My Name — on The Late Show With Stephen Colbert. Then, over on The Tonight Show Starring Jimmy Fallon, you had Fallon, The Roots and assorted members of the Star Wars universe — including the late great Carrie Fisher, which suggests this clip has been around for a while or CGI effects have really advanced — all teaming up to sing the series’ soaring signature theme. If that wasn’t a coincidence, the late-night TV music gods are more powerful than I have assumed until now. But really, I don’t care who or what was behind that dynamic duo of outstanding performances. I would just like to see more of it. Ball’s in your court, TV gods.
