When "The Voice" 2016 continues Dec. 12 on NBC, the top four contestants --We McDonald, Sundance Head, Josh Gallagher, and Billy Gilman-- will take part in the season 11 finals. The evening of vocal action will prove especially challenging for the quartet, as all four will perform three different tunes for America's votes: an original song, a cover of a hit by another artist, and a coach's duet. Here's a look at what the finalists will perform, per song spoilers posted to the iTunes store the morning of the live show.

As usual, each contestant will cover a song made famous by another artist. This season, all four will take on songs that were written more than 30 years ago. The selections for the finals are as follows:
