Geoff Ellis, Dawn Zhu and Billy Boyd have backed the campaign

Christian Aid is hoping to set a new world record for the number of drummers playing simultaneously round the country to back the campaign.

The development agency claimed that IMF and World Bank rules were forcing poor countries to compete against rich ones.

People attending the Kinross music festival have urged to take part.

Christian Aid said international trade rules "forced" poorer countries to open up their markets, but they were unable to compete against countries with more money.

The agency said the UK Government should not be supporting those requirements.

The Beat Goes On campaign, which follows on from the Make Poverty History campaign, has been backed by several celebrities including Scots actor and Lord of the Rings star Billy Boyd.

He said: "It is essential that people keep the pressure up.

"If we all keep drumming home the message that the world's poorest people deserve fairer treatment than they're getting, our leaders will be forced to listen.

"This is a great way, and a great time, to make some noise about the inequality in the world."

'Natural extension'

The campaign aims to set a new record by involving more than 10,102 simultaneous drummers at midday on 8 July at venues also including London, Glasgow, Manchester and Cornwall.

Geoff Ellis, of T in the Park organiser Big Day Out, said: "This is a great chance to show that the festival is internationally aware.
