Angela / JJ / People

After scouting Bootlegzone for info on versions of John Lennon's Angela from the Some Time In New York City album, I learned a few things but got more confused as well. How many versions, excluding officially released, is there of this song? Here's the data. I'm rather skeptical these are all different versions but since Whatever Gets You... has like 34 takes anything's possible:
