One of this album's many joyous highlights is the awesome cover of Frank Loesser’s “Baby, It’s Cold Outside” – an endearingly sweet duet performed by Chris Colfer’s character Kurt and his openly gay love interest Blaine (played by Darren Criss). The kids also give “You’re a Mean One, Mr. Grinch” a splash of Broadway inspired pizzazz, while “God Rest Ye Merry Gentlemen” reveals they can easily hold their own as an a cappella act.
