Jack Smith, known as "Whispering" Jack Smith, was an American baritone singer who was a popular radio and recording artist. He was at his most popular during the 1920s and 1930s, making a brief comeback in the late 1940s. He made occasional film appearances.

"Me and My Shadow" is a 1927 popular song. Officially the credits show it as written by Al Jolson, Billy Rose, and Dave Dreyer, with Jolson and Dreyer being shown on the sheet music as being responsible for the music and Rose the lyrics. Al Jolson was often given credits on sheet music so he could earn more money by popularizing them, but he played no actual part in writing this song. Jolson never recorded the song although he did use it in the touring version of "Big Boy" in 1927.
