Speaking about how the school bagged both celebrities to appear in the video, teacher Noel O'Sullivan said: "The video was an idea of a colleague of mine Oisín O' Connor, a young man who is very talented with a camera.”
“We took a week at it and it coincided with Paddy Casey visiting the school the day after performing at a concert in St Brendan's College with well-known accordion player Liam O'Connor, who is Oisin's father.”
“A few days later, Michael Fassbender was visiting various schools as he is very generous with his time locally.
“We nabbed him for a few minutes during his visit and he really got into the spirit of what we were doing. We chose to support Concern's Horn of Africa fund because it is a very apt cause, considering the song we were singing."
