On December 21, 1978, Carter hosted the annual White House Christmas party with special guests Jim Henson, Kermit the Frog, and Big Bird who sang songs with Sesame Street composer Joe Raposo on piano accompanied by the United States Marine Band.
In thanks for his participation, Carter sent Jim Henson a letter on White House stationary:
The children's party was special! Thank you so much for coming to the White House — with your "creations" and performing for us.
Jimmy and I both send best wishes to you and your family for a Merry Christmas and a Happy New Year.
