Tina Fey and Amy Poehler: Sneak peek at Globes

Tina Fey and Amy Poehler are always in sync.

But always singing in the right key? That's another story.

In the first promo video for the 2014 Golden Globes, the dynamic comedic duo showed off their familiar deadpan humor ... and some pretty poor vocal skills.

With Poehler seated at a piano and Fey standing upright, the pair were supposed to sing a preview of the opening song they supposedly wrote.

But those watching the promo during Thursday night's "Sound of Music Live!" never got to hear the track as Fey and Poehler couldn't agree on the key. (You can watch the video here.)

Thankfully, they have a few weeks to practice. The nominations for the Golden Globes will arrive on December 12, followed by the 71st annual Globes on January 12.

This will be Fey and Poehler's second time hosting the awards show; their work at the 2013 ceremony was so on point, the Hollywood Foreign Press Association booked both of them for the next two years.
