The Late Late Show is rounding-off an unprecedented year with a whopper of a show Friday in support of the Simon Community.
Ten years ago, Glen Hansard first took to Grafton Street with an ensemble of well-known musician friends to raise money for Ireland's homeless, a tradition that he has kept going since.
This year, the traditional Christmas Eve busk cannot take place in Dublin city centre, but The Late Late Show will bring the magic of that Grafton Street evening directly into viewer's homes in aid of the Simon Community.
U2's Bono and The Edge will join Hansard on the show as well as Hozier, Danny O'Reilly, Roisin O, Declan O'Rourke and Kodaline's Steve Garrigan.
Imelda May will join from London for a very special performance of On Raglan Road, with John Sheahan, Finbar Furey, Lisa O'Neill, Hansard and Shane MacGowan joining in from The Late Late Show studio.
Speaking about the show host Ryan Tubridy said: "This will certainly be a night to remember with the best of Irish talent in one room coming together for some incredible performances.
"In return, our friends here are asking viewers to dig deep to donate to the Simon Community and to help our brothers and our sisters who are currently homeless to get off the streets, to be safe, to be warm, to be treated with dignity and decency and ultimately to get the type of secure housing that everyone deserves."
