"What a Wonderful World" is a song written by Bob Thiele and George David Weiss. It was first recorded by Louis Armstrong and released in 1967 as a single. In April 1968, it topped the pop chart in the United Kingdom, but performed poorly in the United States because Larry Newton, the president of ABC Records, disliked the song and refused to promote it.

George David Weiss was an American songwriter and arranger, who was a president of the Songwriters Guild of America.
