These three demo tracks and one studio rehearsal clip are from tapes of Roger Steffens’ KCRW (Los Angeles) Bob Marley Day broadcasts from the mid-1980s.  These tracks were sourced directly from the KCRW tapes to cassette tape.  I do not know who did the transfer.  I came across these gems while looking through my archives for something to post.  According to the INFO.txt file, the lineage is:
