'Men in Black' is a complete and releasable song (with Michael Jackson's vocals on it).
Author Adrian Grant heard the song, and he particularly praised his vocals on the song.
Michael Jackson co-wrote 'Alright Now' for his 'Dangerous' album, but it is not known if he (vocally) recorded it.
There is also misinformation spread by
@dethorro and
@AlwaysThere, such as their false claim that Michael Jackson recorded vocals on a song (called 'Remember What I Told You') on June 19th, 2009.
Michael Jackson was in no position at all to function on a basic level on that day, let alone record vocals on a song.
Show director Kenny Ortega testified that on June 19th (2009) he sent the singer home because of his very bad mental and physical health.
"
It was scary…I couldn't put my finger on it…Michael, is this the best place for you to be or do you want to go home and be with your family?" (Kenny Ortega)
Michael Jackson did absolutely nothing on that day, other than exhibiting a very strange behaviour which alarmed people close to him.
