The had a choral (acapella group from UC Berkeley, CA on the show. They sang a Killers song some other songs. I was not able to catch cause of work so any way I went to their website http://decadence.berkeley.edu/index.html and I saw they sang Mysterious Ways which is not that bad. http://decadence.berkeley.edu/clips/02mysteriousways I just wish you could buy each song individually.
