The Dublin singer-songwriter will also take part in a one-hour music special, 'Shine: A Summer Concert', which airs on Ireland’s RTÉ One on Saturday, August 29.
The special one-off show will broadcast live via YouTube on July 30 and time-zoned to specific regions around the world.
The new track is the singer-songwriter's first new music since his chart-topping debut album, 'Without Fear'.
The event will be live-streamed via the artist's official YouTube channel on Wednesday, 20 May, from 9pm BST.
This year's event was due to host stars including Sam Fender, Rage Against The Machine, Liam Gallagher and Dermot Kennedy.
This year's event is a virtual festival. BBC Radio 1 and the world’s biggest artists will be joining fans remotely while they stay at home.
The EP is a selection of live, re-worked versions of tracks from the artist's UK chart-topping debut album 'Without Fear.'
All the profits from this very special release are going to Ireland's ISPCC Childline.
The weekly Facebook Live Watch Party, presented by Fiat Chrysler Automobiles, will include performances, Q&A sessions, and more throughout April.
Stormzy, Liam Gallagher and Rage Against The Machine have also been confirmed as this year's headlining acts.
The events, also featuring Louis Tomlinson, Sigrid and more run at intimate venues across London from 8 to 22 February.
