Social Firms UK, the national support agency for Social Firm development, has taken an innovative approach to Social Enterprise Day 2008. To reach as many young people as possible, it is releasing a single designed to appeal to youngsters of all backgrounds and to add some fun to the Enterprise Week's 'Make Your Mark' initiative. The single, 'Make Your Mark', has been produced for Social Firms UK by London-based social enterprise Core Arts and performed by Michael Clarke and Michael Collingbine.
