i thought that was a common cd a while back, I remember always seeing it on musicrecyclery.com.. I believe he's affiliated with Mc Mack from memphis...I'm not sure about the value of that cd.
The CD became rare, but it didn't become expensive. I bought my copy on eBay for ~14$ (including Shipping to Europe).
I guess that was about a year ago, so maybe it has a higher value now.
