Of the more than 1000 festival-goers who pledged their support of the campaign, 100 won tickets in a prize draw for Archer's intimate gig. A reknowned solo artist, Archer is also a former member of the band Snow Patrol.
Nigel Varndell, The Children’s Society’s Director of Church Partnerships, said: 'There has been a long history of great music being used to promote great causes. It is pleasing that The Children’s Society and Iain Archer can add to this legacy.'
The Make Runaways Safe campaign was launched in July in a bid to ensure that children and young people who go missing have a safety net. More than 100,000 children under the age of 16 run away from home each year.
The Children’s Society also ran a number of seminars, conversations and activities at Greenbelt. These were devised to highlight issues faced by children and young people today, including running away from home or care, as well as children's well-being.
Greenbelt is a Christian arts festival attended by over 20,000 people each summer. The festival boasts over 650 events including music, comedy, poetry, talks and drama.
