The lyrics for "Mary, Did You Know?" were written by Christian singer and comedian Mark Lowry, after his pastor asked him to write a Christmas musical for their church. Southern gospel musician Buddy Greene later added music to his words.
"White "Christmas" was so popular that Bing had to re-record the song five years after the original 1942 recording because the original masters had been worn out from all the pressings. This is the version that became a holiday tradition.
