Chiddy Bang wowed a large Dance Tent crowd at Reading Festival by freestyling.
They asked those inside the tent, still dripping from earlier downpours, for a few words to get into the rap.
"What's your name? Alan?" they said of one request, a big cheer went out in the Dance Tent, "who else is called Alan?" Most of the tent cheer and put their hands up.
The group freestyle Alan, ice cream, Harry Potter and a few other crowd suggestions over Tinie Tempah's 'Pass Out' to huge applause.
"I need everyone in the whole tent to create pande-fucking-monium," ordered Noah Beresin for 'Here We Go' and the crowd responded in emphatic style.
'Ice Cream Man' was greeted with huge cheers and Chiddy saved some reward for the crowds energy, "make some noise for yourselves."
Ending on their version of MGMT's 'Kids', sweaty fans bounced along in unison to one of the best sets the stage has seen so far today (Sunday).
Reading Festival 2010continues with sets from Cypress Hill, Paramore, Blink 182 and many more.
