Kodaline joined the High Hopes choir for an impromptu singalong on O'Connell Street yesterday.
Ireland's first ever homeless choir was put together by David Brophy for a series on RTÉ and the group got a special surprise when the band joined them for a rendition of their hit single
High Hopes.
The High Hopes Choir cover is currently on sale on
iTunes, with all proceeds going towards homeless charities including Dublin Simon Community, Saint Vincent De Paul and Focus Ireland.
This is what Christmas is all about!
