“Jesus, Oh What a Wonderful Child” is a Christmas gospel song, likely of African American origin (see Dean McIntyre’s hymn study for more information). It gained popularity in 1994, when Mariah Carey sang it on her Merry Christmas album.
The video below features a duet performance by Kelly Clarkson and Fantasia Barrino for the 2004 American Idol Christmas special, filmed in Pasadena, California.
The “largeness” of that performance, I think, really expresses the celebration aspect of Christmas. But if you prefer your music more pared down, you might like Pageant Music’s a capella version “Jesus,” from their 2007 album Word>>>Flesh.
