On the Rocks survives to final five

On the Rocks, the all-male a cappella group from the University of Oregon, survived another round of "The Sing-Off" Monday, and remains in the hunt for a $100,000 prize and Sony Music recording contract.

The 15-member group of current and former students won over judges with an exuberant performance of "Pour Some Sugar on Me" by Def Leppard, part of a set of rock hits, and a soulful version of "Kyrie" by Mr. Mister, which was included in the groups' set of "guilty pleasures." Five groups remain in the competition, out of 10 that began.

"You got the girls all hot and bothered," judge Shawn Stockman said of their gyrating performance of "Pour Some Sugar on Me."

"You can't not smile watching you guys," judge Ben Folds said. "It was fun from beginning to end."

Folds praised the group for bringing some artistry, and not just showmanship, to their performance of "Kyrie."

"The harmonics were pretty sweet," he said. "I don't even like that song, and that was amazing."

The next installment of the five-episode series on NBC airs from 8 to 10 p.m. Wednesday. The live finale airs Dec. 20.
