Peyton Manning Sings Karaoke, Busts Out 'Rocky Top'

Peyton Manning's still showing off his skills ... in the karaoke department, 'cause he jumped on a stage to bust out his old University of Tennessee fave "Rocky Top."

Manning hit up Winners -- a popular Nashville honky tonk -- on Monday night and joined country star Lee Brice and his band to sing lead on the Volunteers' traditional song.
