One of the highlights last night on 'The Voice' was an Aerosmith-inspired rendition of 'Dude Looks Like a Lady' performed by finalist Terry McDermott and his coach Blake Shelton.
The duet was made even better by the surprise appearance of bare-chested guitarist Adam Levine, who was sporting a long wig and bandana.
A poignant moment at the beginning the Monday's final round of competition featured the coaches singing 'Hallelujah' to honor the Sandy Hook fallen.
Tonight one of the remaining three finalists will be crowned this season's winner on the hit NBC show 'The Voice,' airing at 9/8c.
