Peter Tosh - Shajahshoka - who?

[gbougard]

On the recently released deluxe reissues of Peter Tosh's "Equal Rights" and "Legalize it" albums, several dubplate versions are labeled "Shajahshoka Dub Plate". Anyone has any idea who this shajahshoka could have been? Since I bought the albums on itunes because I couldn't wait for the CD to ship, I don't have a booklet which may contain some explanation...

Thanks in advance for any lead.
