Hi--I hope someone can help me--I have a cassette tape set of The Mormon Tabernacle Choir singing Christmas carols--in it is one that is so beautiful--it is called, simply, "Lullaby." I have tried to find out if the sheet music or even the choral music is available for this number and no one has answered me--does anyone out there have any ideas about this piece of music? I would love to have it for my collection--

Thank you.
