Watch 'Game of Thrones' actors sing Tom Waits

Winter may be here, but several "Game of Thrones" actors recently kept warm by crooning covers in between shots. In an Instagram video posted by Kristofer Hivju, who plays the wildling Tormund Gianstbane, four of the "Magnificent Seven" pluck on guitars and ukuleles while covering "I Hope That I Don't Fall In Love With You" by Tom Waits. Check out the video above.

The short clip taken outside of a trailer shows Richard Dormer (Beric Dondarrion) playing ukulele alongside Iaian Glen (Jorah Mormont) on guitar, while Rory McCann (Sandor Clegane) and Hivju look on. The group appears to be in full "Beyond the Wall" garb, likely sitting down to jam between takes of their epic voyage to the northernmost parts of Westeros.

Hivju calls the singing actors the "BROTHERHOOD WITHOUT BANJOS", alluding to the Beric-led group of outlaws known as the Brotherhood Without Banners in the show. "Our new album is called: 'What will fate bring us???,'" Hivju later writes on Instagram.

It's not the first time the group sang together. Last month, Hivju posted a cover of himself and McCann covering "Yellow Bird" by Brothers Four. In the video McCann plays guitar and sings while Hivju offers backing vocals on the 1960 hit song.

The eighth and final season of Game of Thrones will start filming in October. While no official release date has been announced, we can only hope the singing Brotherhood returns to fill the huge void the show has left behind.
