Kacey Musgraves : I love working with Willie Nelson. I’m a huge fan of his, and I was so happy to have him be a part of this funny little song. The title came to me one day when I was heading to a writing session, and it just popped out really fast and really funny; we laughed the whole time that we wrote it. After we were done, I sent it over to Willie and I was just like, “Look, I don’t know if you think this is funny or not, but I think it’s so cute and I would love to have you join me on it.” He was happy to. He played guitar and sang on it, and I just think it’s a really fun, reggae, Willie Christmas song.
