Retired tennis ace John McEnroe showed off his impressive vocal skills on Wednesday (03Aug11) when he rocked out with Kid Rock during a karaoke session in California.
Rock took the stage with Rage Against the MAChine star Tim Commerford at Malibu's Cafe Habana and entertained the crowd by belting out a string of hits by the likes of Metallica, the Sex Pistols and Led Zeppelin during the venue's weekly karaoke party.
But they weren't the only performers in the house - McEnroe also took part in the sing-a-long.
A source tells the New York Post's Page Six column, "McEnroe joined in on many of the songs, they sang 'til closing."
