These are the young Irish singers who joined rock star The Edge on stage in the Sistine Chapel.
The seven teenagers - Abbie Kelly, Claudia Sheehan, Nicole Alcock, Joe Jennings, Cillian Dooley, Naoise Hughes and Katie Brennan - were selected from U2's Music Generation programme to perform in the spectacular setting.
Rosaleen Molloy, national director of Music Generation, attended the exclusive concert and said the performance was so powerful some attendees were moved to tears.
"It was really quite spectacular and something very, very special," she said.
"The performance that they gave was particularly memorable.
"The young people performed with such professionalism and the blend of their beautiful voices with The Edge was very, very special.
"There were many people in tears because it was just so powerful."
The youngsters hail from Carlow, Mayo and Cork city and are aged between 13 and 16.
They were asked if they would like to perform in Vatican City several months ago.
"Some months back The Edge extended an invitation to work with some of the young musicians for the performance," Ms Molloy explained.
"It was quite amazing, a once-in-a-lifetime opportunity for these fantastic young ambassadors. They really made history," Ms Molloy said.
The Edge and the young choir sang four songs, Leonard Cohen's If It Be Your Will and versions of three U2 songs, Yahweh, Ordinary Love and Walk On.
Pope Francis was not present for the show that marked the final day of a medical conference over the weekend.
The U2 guitarist is the first rock star to perform in the historic venue.
The Edge said he was shocked when he was invited to perform in the chapel.
On stage he jokingly told the crowd that there was usually "this other guy who sings", referring to Bono.
He also paid tribute to the Pope and thanked him for allowing the group the use of "the most beautiful parish hall in the world".
Music Generation is a music education programme that U2 partially funds, along with the Government and the Ireland Funds.
