I haven't found anything by Marley. But more than half the tape reels and most of the acetates are either unmarked, or the markings are illegible.
Judging by the scan you posted above, the Marley master tape was not recorded at Fine Recording Studio. Only the acetate was cut there.
Checking in to see if there was any news regarding the Fine Recording tapes; I was hoping that both sides of the Young Tyrants 45 (plus any other unreleased YT tracks?) would surface on a compilation somewhere...somehow!
