Stevie Nicks and Tom Petty rock the stage in London

If you needed proof that you’re never too old to rock out, take a look at Stevie Nicks and Tom Petty on stage at the British Summer Time festival in Hyde Park.

The two music legends had the crowd in the palm of their hands with their rendition of Stop Dragging My Heart Around, belting out the tune and entertaining the masses.

Petty proved his guitar skills are just as slick as ever, while Nicks nailed the vocals.

Petty was listed on the festival lineup and had drawn a huge crowd on his own. But people literally came running towards the stage when Nicks walked on for the surprise duet.

Prince Harry was photographed enjoying American band The Killers, who performed on Saturday, with a group of friends. Harry has attended the festival in previous years and appeared relaxed as he enjoyed a beer with his buddies.
