The Sing Off

What did I miss on the first half hour of The Sing-Off tonight?

For some reason, I thought it was on Fox tonight, not NBC, so I missed the first half hour because I was watching SYTYCD instead b/c I thought "okay, well maybe it's on at nine tonight." :/ So, What did I miss? I came in just at the end of, well, I can't remember the name of the group at the moment, but it was just before a commercial break & right around 8:30.
