Kid rocks at Detroit birthday bash
Kid Rock has taken to a stage in Detroit to celebrate the big 40 with a fitting song - Birthday by the Beatles.
Tens of thousands of his fans filled Ford Field on Saturday night to help the home town rocker celebrate.
The special birthday concert in honour of the man born Robert Ritchie sold out in 19 minutes - a sign of the following the star commands in his home town.
And Kid Rock didn't disappoint.
Early in the show, Uncle Kracker joined Rock on stage for Good To Be Me, and talk show hosts Conan O'Brien and Jay Leno appeared on the two oversized video screens on either side of the stage in taped messages wishing their friend a happy birthday.
O'Brien told Rock: "Happy 40th birthday ... and rock on Detroit!"
