The one-hour musical special features outstanding performances of holiday songs by the incomparable pop diva herself - Mariah Carey - including a duet with 11-time Grammy Award winner Kenny “Babyface” Edmonds. Emmy Award winner Kelsey Grammer gives an unforgettable reading of “The Night Before Christmas.” Billy Gardell (“Mike & Molly”) appears as Santa Claus. Additionally, cast members from “A Christmas Melody” - Lacey Chabert, Brennan Elliott and Fina Strazza – join the festivities sharing holiday memories and experiences from working with Mariah on-set during production of the movie.
Unfortunately the movie Mariah Carey's Merriest Christmas is not yet available on Disney Plus.
