Title: Johnny Mathis (album)
Passage: Johnny Mathis is the debut studio album by vocalist Johnny Mathis that was released by Columbia Records in 1956.  The subtitle "A New Sound in Popular Song" can be found on the back cover but not on the front of the album or the disc label; in fact, this Mathis LP has been referred to as "the jazz album".
Title: When a Child Is Born
Passage: "When A Child Is Born" is a popular Christmas song.  The original melody was "Soleado", a tune from 1974 by (alias Zacar), composer for Italy's Daniel Sentacruz Ensemble, and Dario Baldan Bembo.  The tune was based on Damicco's earlier tune "Le rose blu" published in 1972.  The English language lyrics were written a few years later by Fred Jay (Friedrich Alex Jacobson IPI number 00015195204, who wrote many hits for Boney M such as Rasputin and Ma Baker).  They do not make specific mention of Christmas but the importance they attach to looking forward to the birth of one particular child somewhere, anywhere, suggests a reference to the birth of Jesus Christ, and the citing of "a tiny star" that "lights up way up high" may allude to the Star of Bethlehem.  Fred Jay's lyrics have been sung by many artists, most successfully by Johnny Mathis in 1976.
