The thing about those old links, you can sometimes revive them (or parts of them) with the "Wayback Machine" of the Internet Archive.

Here is the saved copy that the Wayback Machine has of that page. The Geocities pages where midi files were originally stored are long gone, so unless you have files you can send to Joe so he can put them up, that may be lost. And on the bottom of that page you can see a shot of the old Mudcat homepage. That should give a few folks a warm and fuzzy feeling!
