Who is the original singer by o holy night Christmas song?

Answer 1

"O Holy Night" ("Cantique de Noël") remains one of the world's most beloved Christmas carols. But in 1847 it started with a French poem written by Placide Cappeau, a wine merchant, mayor of the town, and an occasional poet, who had been asked by a parish priest to write a poem for Christmas mass. In a dusty coach traveling down a bumpy road to France's capital city, Cappeau considered the priest's request. Using the gospel of Luke as his guide, Cappeau imagined witnessing the birth of Jesus in Bethlehem. Thoughts of being present on the blessed night inspired him. By the time he arrived in Paris, "Cantique de Noel" had been completed.

Cappeau decided that his "Cantique de Noel" was not just a poem, but a song in need of a master musician's hand. Not musically inclined, the poet turned to one of his friends, Adolphe Charles Adams, for help, when he arrived in Paris. Adolphe Adam composed the music for the poem.
