If it were me I would email this guy and ask him if he can be of any assistance. I bet he could :P

If this opens for you, you can scroll down to disc. 3 and click on No. 5 which is Barrel House by Fats...it's an instrumental. I hope this works.
This link doesn't work for me when I put it in the Search box. I got there by putting Barnes Noble.com in Google, and clicked on Music in the second listing for Barnes & Noble. In the search box, I typed Barrel House Fats Domino, and an album came up titled, "Out of New Orleans". I clicked on "Out of New Orleans", and all the listings in the album showed up. That's when I scrolled and found Disc 3 and Barrel House at no. 5.
