Ana Gasteyer can sing -- and we're not just talking about her hamming it up with Will Ferrell on Saturday Night Live.
Although she made her name as a comedian, Gasteyer is a classically trained singer as well -- although she didn't really sing in Fox's Grease: Live!, she's owned the stage in musicals like Wicked and Rocky Horror. A versatile vocalist, she can swing between genres vintage and modern within the space of a single song.
Today, Billboard is exclusively premiering a clip of Gasteyer singing Carrie Underwood's "Before He Cheats" from the new music TV series The Kate. Gasteyer gives the 21st century country hit a smooth jazz makeover, sounding and looking like she's singing in 1950s Manhattan lounge -- she even wraps with a bit of "Fever," the sultry ballad made popular by Peggy Lee.
