"O Holy Night" is a sacred song about the night of the birth of Jesus Christ, described as 'the dear Saviour' in the original, and frequently performed as a Christmas carol. Originally based on a French-language poem written in 1843 by poet Placide Cappeau, it was set to music by composer Adolphe Adam in 1847. The English version, with small changes to the initial melody, is by John Sullivan Dwight.
