Listen to the Cast of 'Glee' Covering John Lennon's 'Do They Know It's Christmas?'

Listen to the Cast of 'Glee' Covering John Lennon's 'Do They Know It's Christmas?' Good Lord. It just arrives earlier and earlier every year. First Justin Bieber releases a music video from his upcoming Christmas album, and now the "Glee" cast has released the first single from their upcoming Christmas album as well.

For everybody who's excited for the Fox musical's second Christmas collection, just about all the New Directions kids have started the hype train with a cover of John Lennon's "Do They Know It's Christmas?" featuring Corey Monteith, Kevin McHale, Naya Rivera, Mark Salling, Heather Morris, Amber Riley, Lea Michele, Chris Colfer and Jenna Ushkowitz.

Even if a late Beatle's Yuletide Third-World-Problems guilt trip isn't your bag, the remaining selections actually look pretty interesting, too. The prospect of hearing the rich-voiced Riley belting out the Mariah Carey modern favorite "All I Want For Christmas Is You" has itself some definite possibilities.

As does Rivera pulling off what I'm sure will be a good and sultry "Santa Baby." There will even be appearances from "Glee Project" competitors Lindsay Pearce, Alex Newell and Samuel Larsen.

My pick for quite possibly the pick of the litter, though? Morris singing "Christmas Wrapping."
