'The Ballad Of Ronnie Drew' was recorded as a special tribute by some of the most famous acts in the Irish music industry.
Tonight will mark the television premiere of the track, as many of the artists who featured on the original recording – including U2, Andrea Corr, The Dubliners, Sinéad O'Connor and Kíla – take to the stage on tonight's Late Late Show on RTÉ One.
'The Ballad Of Ronnie Drew' was released this week and is available as a digital download from today, and will next week be out as a physical CD single.
All profits from the sale of the single will go to the Irish Cancer Society.
The song was written by Bono, The Edge, Robert Hunter and Simon Carmody. Find out more about the story behind the project here.
The Late Late Show airs at 9.30pm tonight on RTÉ One.
