Listen: Gracie Abrams shares demo of new song 'Abby'.

"This isn’t a Christmas song, but it makes me feel some of the things I do around this time of year," explains Gracie Abrams about the demo she's shared of a new song, 'Abby' - that she wrote for her cousin.

Abrams continues: "Grateful and a little wistful. I wrote it to my cousin when she went off to college. Aaron Dessner and I spent about one whole hour on this demo start to finish on a day we were actually meant to be finishing the album, so I hope you like this little something before the real somethings are yours. Very soon. Thank you for sticking with me. I love you very much. Happy holidays ♥️"
