Good stuff, thanks, although these actually aren't the ones I was after.
The dubs on the tape are of a slightly different style, more typical dubwise style, echoed to oblivion.
I guess they could be Fatmans own dubplates which may explain why no one has copies. Shame really. The Jahovia mix is far better than the released 12, as is rasta pon top.
I'll keep searching and let people know if I find them.
Thanks again for the upload.
