The Waterford Institute of Technology (WIT) Youth Choir is made up of 50 singers from secondary schools all over the South East. Singing from their own homes, they've performed a song called "North" by the band Sleeping at Last, which was then put together by their conductor Niall Crowley. It's in memory of choir member Karl Kirby who died recently. Niall chatted to Mary "On the Fringe."
