“One Small Child” is a Christmas song that came out of the 1970s, originally by David Meece. His recording isn’t bad, but by now it sounds very dated. I don’t know if Mark Hayes, who arranged the choral setting, did so in the 1980s, but I do remember singing this for my school’s Christmas program in 1987. My teacher was a very talented musician herself, and had us sing an arrangement similar to this (two groups, though I don’t think we were split boys and girls since none of the boys were strong singers) with a simple piano accompaniment. There are a number of “professional” versions out there, it’s just that this sounds the closest to memory for me. (Reminds me of historical antiphons, but that’s just me being a geek.)
In addition to the “Carol of the Bells” playlist, I’ve started a general playlist of Christmas songs that will include pieces mentioned here, for anyone interested.
