One of American composer, band leader, and electronic instrument inventor Raymond Scott's earliest and most-successful commercial jingles was "Be Happy, Go Lucky" for Lucky Strike cigarettes. A special Christmas modification was made to the tune for the 1950s TV show, YOUR HIT PARADE.

An interesting aside: the holiday version of the carton's packaging was crafted by another influential Raymond, the famous industrial designer Raymond Loewry.
