The two choirs face their first public performances in Dublin's GPO and John Roberts Square in Waterford. David Brophy reveals to the choirs that their next challenge will be to join forces and record a charity single with the RTÉ Concert Orchestra. During rehearsals, the choir members get support and encouragement from Westlife's Shane Filan, chart-topper Ed Sheeran and The Voice of Ireland's judge Bressie. While the choir is recording their charity single in studio, Ed Sheeran pops in to give some last minute advice.
