This track is one of the few pieces I’ve heard that has an optimism about the future, a future with something to look forward to. Louis Armstrong is a well-known musician, who started as a trumpeter, and made some great music with his raspy,deep voice. The song uses jazz chord progressions, trumpets, and soul-stirring strings that enhance the impact of the lyrics . The beauty of this song is that it has succeeded in standing the test of time, and still gives people hope. And that is truly the mark of a great song.
