"Blue Christmas" is a Christmas song written by Billy Hayes and Jay W. Johnson and most famously recorded by Elvis Presley, although it was first recorded by Doye O'Dell in 1948. It is a tale of unrequited love during the holidays and is a longstanding staple of Christmas music, especially in the country genre.
