Interesting fact:

"Jingle Bells" was the first song to be ‘performed’ in space! In 1965, astronauts Walter Schirra Jr. and Thomas P. Stafford were orbiting earth and reported to have spotted a strange UFO in a red suit, travelling with eight smaller UFOs in front. They then produced bells and a harmonica, that they had stashed away, and began to play “Jingle Bells.”
