As March, 2019 some of the tabs are back up again. I mistakenly deleted the page in 2018. What I have done is looked up the page on the Archive and most, but not all, of the links work. (None of the links in the green box work.) I have PDFs for anything that's on the page but the link is broken and am glad to put up where it can be downloaded or emailed. Email me at email@example.com. Give me a couple days or so because I'm not always available to answer that address.
One of the tabs that the link is broken is Mississippi. It can be downloaded here: http://www.mofrofans.com/f/mississippi.pdf
This page gets an average of 30 views a day (many keyword variations of JJ Grey and Mofro tabs, JJ Grey guitar tabs and the like.)
