The choir made their debut in front of the audience at Hard Rock Hotel & Casino's Etess Arena to sing 'Jesus Oh What a Wonderful Child' with Mariah's longtime backup singer Trey Lorenz.

They stayed for 'Silent Night' to sing with Mariah, and returned for the night's big closing number 'All I Want for Christmas Is You'. See some video below!
