This classic music is about 100 years. Words were written by Eben Rexford, who sold them for USD 3 (that times, this allowed to live for pair of weeks). And he earned for living with his pen, occasionally selling songs, poems and writing articles for magazines about gardening. The melody was written for a good and deep voice that sounds naturally only from old records. Especially if they are played on gramophones with big speaker in the form of expanding pipe.
