Here's the lineup for this week's Late Late Show
It is a special musical episode of the show, with many Irish stars performing for the Simon Community.
The magic of The Late Late Toy Show has well and truly died down, and with just days left to go until Christmas, you may be up to your eyes.
However, if you are well prepared for the mad few days ahead, you might want to relax and watch the special musical episode of The Late Late on Friday night.
Ten years ago, singer 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 be bringing the magic of that Grafton Street evening directly into viewer's homes in aid of the Simon Community.
Bono and The Edge will perform on the night, pledging their support for the Simon Community, as will a cast of Ireland's top musical talent including Imelda May, Hozier, John Sheahan, Finbar Furey, Shane MacGowan, Danny O'Reilly, Roisin O, Declan O'Rourke, Lisa O'Neill, Kodaline's Steve Garrigan and many more.
"This will certainly be a night to remember with the best of Irish talent in one room coming together for some incredible performances," Ryan Tubridy said.
"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."
The Late Late Show Busk for Simon kicks off on RTÉ One on Friday, 18 December at 9.35pm.
