I mistakenly deleted this page in 2018. (And I'm still pissed at myself.) So my solution is I have looked up the page on the Internet 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 firstname.lastname@example.org and I will send to you.
One of the tabs that the link is broken is Mississippi. It can be downloaded here: http://www.mofrofans.com/f/mississippi.pdf
As of 2020 this page still gets an average of 30 views a day (many keyword variations of JJ Grey and Mofro tabs, JJ Grey guitar tabs and the like.)
