Hmm. Wiki says this: «I Love the World, also known as I Love the Whole World, is an advertising campaign launched by Discovery Channel in 2008 in promotion of their new tagline: "The World is Just... Awesome".[1] The song used in the ad is a re-writing of a traditional camping song known as I Love the Mountains or I Love the Flowers, sung to the tune of Hoagy Carmichael's 1938 "Heart & Soul", featuring a chorus of "boom-de-yadda, boom-de-yadda".[2]»

But the tune of 'Heart & Soul' ( http://www.youtube.com/watch?v=Y8CSjDC18b0 ) isn't very similar to the one in 'I Love the Word'. Confusing.

Here's Hugh Laurie with his take of it, by the by!: http://www.youtube.com/watch?v=cHJRSKvbiXA
