Last night's performances on "Dancing With the Stars" were inspired by rock hits, and the show opened with a performance by the band Kiss.
NFL player Donald Driver took the top spot on the leaderboard for the first time in the competition. He ripped off his vest and danced a powerful paso doble, complete with pyrotechnics at the end and a Gene Simmons-esque protruding tongue. Driver earned 27 points, taking the top spot on the leaderboard for the first time.
Melissa Gilbert: The "Little House on the Prairie" star performed a fiery paso doble, though she "messed up the ending". Gilbert's partnerMaksim Chmerkovskiy took responsibility for the slight slip-up. At the end of the show, co-host Tom Bergeron said Gilbert had injured herself -- hit her head on the dance floor-- and gone to the hospital as a precaution.

THE LOWEST SCORE:
Gladys Knight: The R&B legend took on the tango to Queen's classic "Bohemian Rhapsody." Knight was awarded 20 points.
