It's a pretty musical Late Late Show tonight as the RTE Concert Orchestra will be performing throughout the show. We don't know why yet, maybe just for the craic.
As well as that, guests include boxer Ricky Hatton, former WBA, IBF, IBO and The Ring Light Welterweight Champion, who will chat to Ryan about the current state of boxing following the Mayweather-Pacquiao fight. (Hatton took on both fighters during his career).
Comedy will be provided by Oliver Callan of Callan's Kicks fame while there will be music by Irish Country superstar Nathan Carter, who has just announced a Christmas gig in Vicar Street.
So yeah, that's all we know for now, Graham Norton looks pretty savage though!
