who wrote the song we wish you a merry christmas

That song was written by John Frederick Coots and Haven Gillespie in 1934. They were both popular songwriters of the time, and they wrote several Christmas songs together, including "You're a Mean One, Mr. Grinch" and "Put One Foot in Front of the Other." The song "We Wish You a Merry Christmas" has been a popular holiday tune ever since it was first published, and it is still sung and performed every year during the Christmas season.
