By the great Percy Mayfield. I learned this "on the street" and may not have all the right lyrics. But it's a great tune for a blue guitar.
But, if you would like to load this song on your iPod® or local system so that you can access it without the Internet, you can download a copy to your local system. I will warn you, these are big files -- they take a long time to download and a lot of space on your system (this (long) video is 20MB, the mp3 is 5.8MB).
