Here’s Michael Crawford (yes, the Phantom of the Opera) singing “O Holy Night,” from a 1993 NBC TV special called “David Foster’s Christmas Album.” It was recorded and is available.

The song was composed by a man named Adolphe Adam in 1847, setting the words of a poem written by Placide Cappeau to music. At the request of the parish priest, Cappeau wrote the poem to commemorate the renovation of the church’s organ in the French town of Roquemaure.
