It seems like just yesterday we were watching Pat Byrne walk away with The Voice of Ireland crown and a recording contract with Universal Music Ireland, and already we've come full circle. Over the past few weeks we've watched thousands of hopefuls battle it out to follow in his footsteps, and now we're down to the final four, who'll battle it out this evening on RTE One, singing the songs that they hope to release as their winner's single.

Taking to the stage for Team Bressie is Shannon Murphy. We'll never forget the first time this redhead from Cork belted out a tune in her distinctive tone, and watching her grow throughout the competition has been a joy. Tonight she'll be giving us her own rendition of The Lumineers' 'Hey Ho', a tune that we're sure even Kian Egan will be familiar with.

Speaking of Kian, he's sitting pretty among his fellow coaches, with two acts left in the competition. First up is Donegal man Shane McLoughlin, who has defied the odds to make it all the way to the final. Shane's taking on old Irish favourites The Frames, singing 'Fake 'to stake his claim for the crown. Could he take the boys back into the Irish charts?

Next up is The Voice's resident baby mama Kelly Mongan, who has had us all on the edge of our seats over the past few weeks. We were just as anxious about her water breaking as we were about her hitting the high notes. Tonight she'll be singing for two from the soul, with what we're sure will be a powerful rendition of Elton John's 'Sorry Seems To Be The Hardest Word'.

And last but not least, Keith Hanley's still hoping to bring the title home for Team Jamelia. We're expecting a rather big production when Keith hits the stage with The Saturdays' version of The Four Seasons' 1967 hit 'Beggin'. And if his past performances are anything to go by, we're sure the Charleville boi will leave his fans beggin' for more. And sure aren't The Saturdays themselves even in town to perform on the night? No pressure Keith!

Each act will also be performing a duet with a special guest: Kelly's taking the stage with our very own Saturday Una Healy, Monaghan singer Ryan Sheridan teams up with Keith, Steve Wall of The Stunning will be Brewing Up A Storm with Shane, and Shannon will sing We Should Be Lovers with Royseven's Paul Walsh.

Of course, there can only be one winner on the night, so don't forget to vote for your favourite. If you're not in, they certainly can't win that recording contract. And remember, you'll be able to download the winning single on iTunes too.

Catch The Voice of Ireland tonight from 6.30pm on RTE One.
