Sittin' on top of the world, part 2
The lyrics are simple and have the most common subject of all music around the world, an abandoned lover (in this case, a thankfully abandoned one). The unique, yet simple chord progression of the melody flows pleasantly to the ear. It's no wonder that this song would find it's way into the repertoire of musicians of just about all American musical styles. Not only did it make the transition to a variety of styles, it became a classic, a standard to be included in many musicians playlists.
In fact, there are so many versions of this song that I had a difficult time selecting examples to post here. If I missed your favorite, I apologize. I could not find my copy of Bob Wills & the Texas Playboys (sorry Greg), nor the Seldom Scene (sorry Lucy). We've had a bit of computer/network trouble on the Bus.
