Amazon Studios have announced the release of Click Clack Moo: Christmas at the Farm, a new holiday special inspired by the acclaimed children’s book series from New York Times bestselling duo Doreen Cronin and Betsy Lewin.

Okkervil River have contributed the theme song titled What Friends Do, of which Will Sheff says, “I listened intently and repeatedly to my favorite kids’ songs by writers like Joe Raposo and Harry Nilsson. There’s something about writing songs tailor-made for kids, I noticed, that brings out something really tender and urgent in adults. The original ‘Click Clack Moo’ book, is about a bunch of farm animals who learn that by banding together they can get the farmer to provide them with better living conditions. So I thought I’d write a song that reflected that message – that if you stand together with your friends and if you stand up for your friends you’ll never feel alone and you’ll be able to get great things on behalf of everybody, stuff that would never be possible to do all yourself.“
