What was Louis Armstrongs most popular song?
Since the movie Good Morning Vietnam came out He experienced A rebirth of His classic What a wonderful world. He is a legend and was in his own lifetime for very good reason and back in the days when musicians got no electronic help whatsoever he achieved legend status with his New Orleans blues sound like Basin Street Blues and St Louis Blues etc. A lot of people will clearly remember his big googly eyes and him mopping his brow while singing Basin Street which I think was his most popular number.
