The show's host Ryan Tubridy will interview band members Billy McGuinness and Christy Dignam and the band will play some songs from their classic album.
It's also a possibility that they will debut a new song tonight due to be released shortly. "The new single 'Now I Know' is coming very soon," Billy told us back in December, revealing that the band are back in the studio working on an EP and also material for a new album.
A band insider has confirmed to Hot Press that Christy Dignam will perform a duet tonight with his daughter, Kiera, of their new single, 'Under Pressure'.
We here at Hot Press just heard the Bowie and Queen cover this morning and it's a great version with strings.
"The plan is to immediately release the new song, 'Under Pressure', after the show," our source reveals.

When Christy last appeared on The Late Late Show almost a year ago, he performed a duet with Finbar Furey of the 'Green Field of France'. It has since become an internet sensation with close to 7million hits on Youtube and Facebook.
