Unless there's an acetate or tape copy in his archives, I think it's impossible to know. Since a few tracks were included on later releases, it's very possible whatever master tape that was assembled for Homegrown was dismantled and never put back together (and perhaps taken apart song by song). If that happened, he could've lost track of certain songs and maybe even remixed particular songs since there was no real reason to keep the old mixes to an album that wasn't going to be released imminently.

Although I get the feeling Neil keeps everything (especially the master tape of an unreleased album), and they could have rebuilt the record to match as closely as possible to the original master.
