Silent Night was a popular Christmas carol. The lyrics were first written by a priest in Austria, Joseph Mohr, in 1816. The music was composed by the local music teacher, Franz Gruber. The song was very popular during Christmas and was translated into more than 44 languages. The original version was slightly different from the modern version, but it was still one of the most popular Christmas songs. In 2011, Unesco declared Silent Night as an intangible cultural heritage. There were many different versions and covers of the song, including versions performed by artists such as Jacky Evanko, Fleming, The Flowers, Teresa Teng, and Wakin Chou.
