Ben and I saw them perform at BYU several times and adored their sound, stage presence and song selections. In fact, we enjoyed them so much I made a meager attempt to make one of them my brother-in-law. (Sadly, my sister didn't end up making the 4-hour drive for the date. *tear*)
This is all to say, we can watch them again! They are performing on NBC's "Sing-Off" on Monday nights. Watch here. It will make you happy. Because, as Ben Folds put it, they are truly sick.
I'm also going to shamelessly request you vote (here) while you're at it. Go Cougars.
