The instant I heard The Lumineers infectious single "Ho Hey" a few weeks back, I was instantly hooked in. Not only did it dominate one of the only good radio stations in Philly, 104.5, but people all over seemed to love it. The song is actually quite short and is my only qualm about it, but that is okay that's what the replay button is for. Anyway, the Denver based band performed "Ho Hey" last night on the Late Show with David Letterman, which should only introduce their folk/indie sound to even more people. Watch below.
