We've always known Hozier was a fairly sound lad despite his skyrocketing levels of fame, and now he's proven that yet again.

The Bray native is one of a host of Irish musicians and entertainers taking part in RTÉ 2fm's Christmas charity appeal, to raise much-needed funds for the ISPCC.

This Thursday December 3, 2fm will broadcast live from the window of Benetton on Stephen's Green, where hosts of each show will be joined by some huge Irish names.

As well as Hozier – who we're hoping will sing a song or two – other guests include Jamie Heaslip, Vogue Williams, Hometown, RipTide Movement and Angela Scanlon.

So if you have a few minutes free on your lunch break or are in the capital to get some Christmas shopping done, stop by the window and you could find yourself watching Hozier perform live – albeit behind a pane of glass.

If you can't make it to Stephen's Green, you can follow the action live on 2fm between 7am and 7pm, or check out the updates on Twitter and Facebook.

Plus, Hozier will be performing at the 2fm Ball at the 3Arena on December 23rd, along with Little Green Cars, Gavin James, RipTide Movement, Hudson Taylor and more. Tickets for the event start at €45 and are on sale now in aid of the ISPCC.

As part of the campaign, listeners can also enter to win an incredible 3Arena Golden Ticket, entitling them to two tickets to EVERY show in the 3Arena and EVERY MCD open air concert in 2016. Adele, Little Mix, Rihanna… you name it.

To enter – and donate to the ISPCC – simply text 2fmBall to 50300 between now and Thursday afternoon.
