Christians across the UK are being invited to vote for their top ten favourite hymns via Christian internet service provider Surefish.

The top ten chosen on the Great Hymn Sing vote will then be sung by Greenbelt festivalgoers on 26 August.

People can vote for their top ten hymns from a list of 114. The 50 hymns with the most votes will then go through to the next round of voting, which will reduce the list to 25.

The final round of voting will decide the favourite top ten hymns, which will be announced and sung at Greenbelt, where the Love and Joy Choir and other festival guests will talk about what singing means to them.

Surefish editor Andy Jackson said: "There's nothing like a really good hymn sing - hundreds, even thousands, of people, singing classical, traditional hymns.

"That is why Surefish is organising the Great Big Hymn Sing at this year's Greenbelt festival, to give those who like singing the chance to vote for and then sing their favourite hymns."

The ISP recently launched a new range of broadband internet services to raise money for Christian Aid's work in developing countries and to help it continue the fight against global poverty.

Surefish, which is owned and operated by Christian Aid's trading arm, has raised more than £500,000 for Christian Aid over the last six years. It now wants to raise this amount every year. With around 12 million people already using broadband in the UK the ISP, it hopes to achieve this by encouraging thousands of broadband users to switch to Surefish.
