From the late 18th century, some geographers started to regard North America and South America as two parts of the world, making five parts in total. Overall though, the fourfold division prevailed well into the 19th century. Europeans discovered Australia in 1606, but for some time it was taken as part of Asia. By the late 18th century, some geographers considered it a continent in its own right, making it the sixth (or fifth for those still taking America as a single continent). In 1813, Samuel Butler wrote of Australia
Somewhere Over the Rainbow/What a Wonderful World World." In 1993, five years after the original recording, Bertosa played the song for producer Jon de Mello while the two were completing work on "Facing Future", and de Mello decided to include it in the album as "Somewhere Over the Rainbow/What a Wonderful World". "Somewhere Over the Rainbow/What a Wonderful World" reached #12 on "Billboard"'s Hot Digital Tracks chart the week of January 31, 2004 (for the survey week ending January 18, 2004). According to the Israel Kamakawiwoʻole website, Universal Studios first became interested in using the song in the movie and on the soundtrack for "Meet Joe Black"
