"When a Child Is Born" is a Christmas song, with a melody taken from "Soleado", a tune from 1974 by Ciro Dammicco (alias Zacar).

Entitled "When a Child Is Born (Soleado)" with the B-side a cover version of the Charlie Rich hit "Every Time You Touch Me (I Get High)", it became Johnny Mathis' sole number one single in the UK Singles Chart, spending three weeks at the top of the chart in December 1976, including the coveted Christmas number one slot, and selling 885,000 copies.

[1] In the US, it appeared in the Record World survey in both the Christmas seasons of 1976 and 1977, reaching a maximum position of No.

The melody was used with German lyrics by Michael Holm in "Tränen lügen nicht" (translation: Tears Don't Lie) in 1974.

The singer asks a guy to reconsider breaking up with his girl because her tears don't lie.
