Country singer Julianne Hough tears through a medley of Night Ranger’s “Sister Christian,” David Lee Roth’s “Just Like Paradise," and Poison’s “Nothin’ but a Good Time” with convincing aplomb., Listen closely and you’ll hear Hough scream like a young Joan Jett, and Jett's hit version of Arrows' “I Love Rock ‘n’ Roll” gets hilariously covered by Alec Baldwin and Russell Brand.
