Once director John Carney is in studio to discuss his new musical film Sing Street, an homage to his youth growing up in the 1980's Dublin. He is joined by Angela Dorgan of the Hard Working Class Heroes music festival. They discuss the role of music both in movies and in the day to day lives of young people, and how the pop of the 1980s helped cut through the occasional dreariness of life in Ireland. Sing Street is released on March 17th. Off Topic is a weekly arts and culture podcast from The Irish Times.
