The Roches are three sisters, who sang as a mostly a cappella trio. Their Christmas record is mostly delightful (though a few tracks are pretty twee). Their Hallelujah Chorus is fabulous, but the haunting Star of Wonder is today's pick.
If you are given to singing around the fireplace or with a chorus, the sheet music for Star of Wonder is on the Roches website - with a note from Terre Roche who says:
I encourage anyone who would like to sing "Star of Wonder" at Christmas time to do so. I consider myself to be the channel through which this little song came into the world. I don't "own" the song. Nobody does. It belongs to all of us! The thought that people are singing "Star of Wonder" at Christmas time makes me feel great!
