Some people say bad things come in threes. Other say it’s good things. But what about average things? Based on Tuesday’s late-night TV music segments, it seems the same rule applies. Of the three acts peddling their wares on the chat shows, only Fifth Harmony’s Lauren Jauregui was truly memorable — chiefly because her performance of generic pop single More Than That on The Late Late Show With James Corden included a pair of pole dancers and a ginormous floral set bathed in purple light. Points for trying, I guess. Meanwhile, on The Late Show With Stephen Colbert, much-hyped pop phenom Maggie Rogers enlisted the aid of bandleader Jon Batiste for the less-than-fiery Burning, one of the many similar-sounding tracks from her meh new album Heard It In a Past Life. Sadly, it’s unlikely to burn its way into your consciousness. Ditto the Brothers Osborne’s performance of their ballad I Don’t Remember Me (Before You) on The Tonight Show Starring Jimmy Fallon. Aside from guitar slinger John Osborne’s too-brief solo, you likely won’t remember it at all. In fact, let’s just forget the whole thing and try again tomorrow, OK?
