Truro Cathedral choristers in the UK have raised £8,434 to enable Unicef to provide over 10,000 Covid-19 vaccine doses.
They were aiming for £5,000 and made the money from a music single released a few weeks ago.
The fundraising event took place as part of the recent Sing2G7 project, where choristers encouraged children to raise their voices in song to world leaders who were meeting in Cornwall for the G7 summit.
Over 27,000 children in 31 countries, signed up to sing 'Gee Seven', written specially for the project by Sir Tim Rice and Peter Hobbs. More than 300 schools across the UK took part as well as churches and cathedrals in the UK and abroad.
All the royalties from the 'Gee Seven' single were given to VaccinAid.
The Very Rev Roger Bush, Dean of Truro, said: "I'm very proud of our choristers. It's a significant sum they've raised for VaccinAid, that really will make a concrete difference in some of the poorest countries in the world. This is a very practical way of loving our neighbour and I'd like to thank everyone who supported the choristers in doing just that."
Thirteen-year-old head chorister Jacob said: "'I can't quite believe that by singing a song we have enabled 10,000 people to be vaccinated. It's amazing. Thank you so much to everyone who made a donation."
