Mark Ronson brings Mary J. Blige and George Clinton onstage for Uptown Funk at Glastonbury

Producer and hitmaker Mark Ronson was joined by Grandmaster Flash, Mary J. Blige and George Clinton as he performed his smash-hit Uptown Funk at the Glastonbury festival on Friday (26Jun15).

Theophilus London, Daniel Merriweather, The View's Kyle Falconer and Tame Impala's Kevin Parker also joined Ronson during his set, but the highlight came when Boy George came onstage to perform a reggae version of Culture Club hit Do You Really Want To Hurt Me?

There was a somber moment as Ronson introduced Valerie, the song he recorded with the late Amy Winehouse, telling festival-goers, "We've tried this song a bunch of different ways but tonight it feels right to play the original vocal that we recorded together.

"Her music lives on. This is a celebration of that. Sing along, sing to the heavens. Nobody will ever top this vocal."
