The five acts were selected from more than 320 entries RTÉ received from an open competition and were whittled down to the final five by two expert panels of music and entertainment industry professionals.
The order in which the acts appear was decided by a draw in January which all the acts were present for. The voting procedure will be independently supervised by Gareth Hynes of Price Waterhouse Coopers.
The voting is as follows. Voting does not open until Ryan says lines are open AFTER all five have performed on the Late Late Show. Do not call or text before that time or you will be charged and your vote won't count.
Equally the votes will close live on the night and you should not vote after that time or if watching on catch up services.

"Playing With Numbers" call 1513 7171 05 or text the word SONG 5 to 53125
The winner will be chosen by a combination of votes from five regional juries and the call and text votes from viewers on the night.
You will be able to vote for your favourite song only when Ryan tells you the lines are open. The numbers will appear on the screen as each act performs, but the lines won't open until after all five acts have performed and you are told the lines are open. If you vote before then your vote won't count but you will be charged...so don't do it, you have been warned!
This is the year I hope to make the show my own. With two seasons under my belt, I'm looking forward to getting the show on the road.
There's plenty of great prizes up for grabs throughout the season. Check out our Competition section for more details...
