Frank Turner leads the karaoke at Leeds Festival

Ex-Million Dead front-man Frank Turner took his seat on the NME/Radio One Stage to lead the masses through a spirited sing-a-long.

Armed with his acoustic guitar, catchy verses and a rebellious message the English singer/songwriter thanked the "gazillion" fans who turned out to join him and chant back every word of his songs.

To close the triumphant set Frank made an unusual request: "I want to see a circle jig…" before the most gentle of mosh pits started to swirl in front of the stage.

Leeds Festival 2010 continues with sets from Arcade Fire, The Libertines and more.
