Here is an interesting site about Jamaican Ginger extract, and its effects. Toward the bottom of the page is a link to realaudio of some of the songs listed by Art. Though the site says that there are 13 titles, they list only 12. Jake Walk Blues is listed, but is missing from the RealAudio as are some of the others, replaced with various moonshine songs. Still, it is a VERY interesting collection, and worth exploring. As they say, just click on the player piano to hear them all consecutively. The playlist is done in clip form, so you can go from one to the next by clicking on next clip.

In addition to the recordings listed by Stewie, there was an LP by the Allen Brothers on Old Timey, and Jake Walk Blues is also anthologized on Are You From Dixie? Great Country Brother Teams of the 1930's on CD by RCA Victor, but the Document CDs is definitely the way to go! I think I will treat myself to an "after Christmas" present of the set.
