Paul McNeive was at a special event in Dublin where the astronaut Chris Hadfield was on stage. Hadfield, who had a viral hit with his galactic rendition of Space Oddity and is a tourism ambassador for Ireland, picked up Paul’s guitar and started playing the traditional song Danny Boy. He explained how much the song meant to him and how he signs it every year on St. Patricks Day, March 17. Credit: YouTube/Paul McNeive
