I am not asking for a copy or how to get a copy. Just asking about how much different sounding it is from the other version?

We have limited information on this at present. It may be little more than the slightest accompaniment here and there. If there is any substantial input by Michael B on the 1989/1990-era version of this song, it is likely to have been mostly or entirely re-recorded. I believe it is the former, and is likely to be underwhelming.
