Which Christmas carol was the first song to be sung in space?

In 1965, astronauts Walter M. Schirra Jr. and Thomas P. Stafford performed a practical joke as they re-entered Earth's atmosphere on December 16. They played "Jingle Bells" with a harmonica and some bells, marking the first recorded song from outer space.
