Hozier may be known for his sombre tone and complex lyrics, but last night the singer-songwriter proved he is full of the spirit of Christmas when he performed a surprise gig for a very special cause.

The Wicklow native dropped into Laura Lynn's Children's Hospice in Dublin to perform for a crowd of parents and children who had gathered for a special Christmas lights ceremony.

He took to the stage alongside Irish indie rockers Ham Sandwich for a touching rendition of Winter Wonderland.

Decked out in his Christmas best, Hozier wore a brightly lit festive jumper, featuring The Animal from The Muppets Show made using felt and fairy lights.

According to Twitter user @RianRyan, the jumper was specially made for him by some of the kids ar Laura Lynn House.

Twitter is flooded with clips from event-goers who captured the magical moment for everyone to enjoy.
