Kings of LeonKings of Leon played an emotional tribute to former 'Jackass' star Ryan Dunn on Wednesday night, June 22, during the encore for their first of two shows in London's Hyde Park.

Dunn, who had become a friend to the band in the past year, was killed in a fatal car accident in Philadelphia in the early hours of Monday, 20 June.

Speaking to the crowd, NME reports that frontman Caleb Followill dedicated 'Use Somebody' to Dunn and led the crowd in raising their glasses to "a friend of ours."

This echoed sentiments tweeted by brother Jared before the performance, saying he was "heartbroken" and "devastated" at the loss of the 34-year-old, whose memorial service also took place Wednesday.
