While Band Aid 30’s ‘Do They Know It’s Christmas’ is currently topping the charts in the U.K., they’re not the only charitable supergroup at work this holiday season.

The Band of Merrymakers -- featuring musicians from Neon Trees, Fitz and the Tantrums, Lady Antebellum, 311, Better Than Ezra and more -- premiered ‘Must Be Christmas’ via Billboard yesterday (Nov. 24).

The song is accompanied by a video, which follows a group of guitar-wielding santas as they parade through the streets of L.A. and Nashville. Watch it above.

You can purchase the song on iTunes, and a portion of the proceeds will go to MusiCares, a non-profit offering emergency financial aid and addiction recovery resources to working musicians.
