Glee Season 2: Grilled Cheesus Song Previews

Here's  next week's episode, Grilled Cheesus, song previews. I wonder why they didn't record R.E.M's Losing My Religion.

Anyway, I'll comment on the songs once the full versions are released. But I can tell that I already love Mercedes' version of Bridge Over Troubled Water and the New Directions' cover of One Of Us.
