Patti Page’s version of the Tennessee Waltz was picked by her to record as the B-side of “Boogie Woogie Santa Claus”. The Waltz was kind of a throwaway pick that quickly overtook the main choice.
Curiously, "Boogie Woogie Santa Claus" has made a comeback in the 21st century. Every Christmas season I hear it several times being played over the radio, as background music at Trader Joe's, etc. However, the version they play is usually Mabel Scott's.
