Some days it’s all about the pop stars. Other days it’s all about the singer-songwriters. In Wednesday’s late-night musical world, it was all about the bands. And you had three choices: 1) Matt Healy and The 1975 stepping up with It’s Not Living (If It’s Not With You) on The Late Late Show With James Corden; 2) Chicago electro outfit Rüfüs Du Sol introducing their synth-fuelled single Treat You Better on Jimmy Kimmel Live; and 3) The Lumineers showcasing their number Gloria (not to be confused with the Van Morrison classic) on The Late Show With Stephen Colbert. Simple as that. Enjoy.
