Ryan Tubridy announced the special on last week's show. "Save the date, people. Wednesday, the 17th March. Wednesday. Not Friday, Wednesday," he said.
The host said: ''we'll be bringing you the lockdown session to end all lockdown sessions. We need a party, so we're going to bring it to you.
"We've enlisted the help of the diaspora, of course - a fancy word, basically, for your cousins, your brothers, your grandchildren, your sisters, your best friend from college who married the guy from Canada and also those proud to call themselves Irish and who are scattered to the four corners of the globe.
"We'll have the cream of Irish traditional music - Brendan Gleeson, Paddy Moloney of The Chieftains, The Corrs and, Clannad, to name but a few.
"We'll be presenting our Late Late Show St Patrick's Day Award to an outstanding recipient, so that's going to be enormous. And so much more happening so do join us on Wednesday night for our St Patrick's Day Special."
Among the guests due to appear on the St. Patricks Day special are Irish band Stockton’s Wing, concertina player Edel Fox, flautist and piper Louise Mulcahy; aswell as fiddle player Zoe Conway.
The Late Late Show St Patrick's Night Special, Wednesday, RTÉ One, 9:30 pm.
