A nice Gospel ballad for Christmas is Oh, What A Night! No, not December, 1963 by the Four Seasons. This Oh, What A Night! is written by the Gospel choral genius (and author of the Gospel anthem Total Praise) Richard Smallwood and its performed by him and the ensemble Vision.
The verses feature a soloist and the choruses can be sang by a vocal ensemble or choir. The final choruses involve a challenging modulation and some countermelodies that may need some extra practice, but this is a good song that will also provide an edifying ear-worm to listeners for the Four Seasons' song.
