And, as if by magic, their song was interrupted by the airport intercom announcing flight boarding details.
Singer Laura Llorens's layover from Paris to Chicago was six hours delayed in Dublin. She made the most of her time by raising the spirits of some of the younger, tired passengers with renditions of 'Ring of Fire', 'Sweet Home Chicago' and 'Sweet Molly Malone'.
Laura spoke to Independent.ie about the singalong:
'I felt that there was a general good ambiance within the terminal- though as the wait and night dragged on, people became more and more impatient and agitated.'
Finally, a request for 'Leaving on a Jet Plane' by John Denver was made and as Laura started to play, the whole terminal chimed in for the chorus and the airport intercom announced that the flight would be boarding. Laura added:
'The music certainly lifted the spirits and I almost want to say that the fact that the whole terminal was singing and bonding through songs made us board that flight. Many people were relieved! It all worked out. Never underestimate the power of a song.'
