In 1994, Paul Newman set up Barretstown, a camp for children and families affected by serious illness. In the last 20 years, the camp has welcomed 27,000 campers, including some of the children in this video.
The song in aid of the charity is the wonderful Bruce Springsteen track, Dream Baby Dream, performed by Joyce Murphy, a former camper herself, along with the help of Mundy and Tom Dunne, who feature in this video.
This is just genuinely heartwarming.
If you would like to help out Barretstown, please head on over to their website. The single will be released on Friday 21st February.
