Grab your pitch pipes -- "The Sing-Off" has announced the lineup for its two-hour finale on Monday night.
Special guests Pat Benatar and Neil Giraldo will sing their 1984 hit duet “We Belong," and season three winners Pentatonix will also return to the stage they conquered in 2011.
Additionally, "Sing-Off" host Nick Lachey will be joined by his fellow 98 Degrees members Drew Lachey, Justin Jeffre and Jeff Timmons to perform “I’ll Be Home for Christmas” from their 1999 holiday album, This Christmas, and also serenades the season's new judgeJewel into a duet of “It Had to Be You."
And following Sing-Off tradition, the final episode also pairs each judge with one of the remaining a cappella groups in the competition: Jewel will perform with professional country group Home Free,Shawn Stockman will take the stage with gospel-infused collective Ten, and Ben Foldswill join performing arts high school group Vocal Rush onstage.
All seven previously eliminated groups -- The Filharmonic, VoicePlay, acoUstiKats, Element, Calle Sol, Street Corner Renaissance and The Princeton Footnotes -- will return to perform as well.
The final night of the revived a cappella competition will feature holiday songs as part of its set list -- an element sorely missed during season three's finale. The episode will crown a season four winner, rewarded with a $100,000 prize and a Sony Music recording contract -- plus the top spot on The Sing-Off's first tour.
