Some of the stars at this year's V-Festival in Staffordshire were seen wearing badges in support of the charity, Always A Chance.
The charity was set up by the friends of James Cooper and James Kouzaris, who were murdered in April 2011.
Olly Murs and Ed Sheeran both wore the charity logo with pride as they entertained festival goers over the weekend.
The importance of anti-violent initiatives was once again demonstrated after a 40-year-old man died at a party opposite the festival site. The death is suspected to be a result of a violent attack and ten men have been arrested.
Always A Chance helps fund projects which work with young people who are at risk of becoming involved with violent crimes.
