To start with "which tracks on For Lover's Only feature Melvin Franklin", I found this online version of a billboard magazine:
The album is created as a tribute to Melvin Franklin, the group's original bass, who passed away in 1995, and it contains his last recording with the group "Life Is But A Dream".
This can also be verified by the record on Discogs,...
Comparing to the picture at http://www.pias.com/blog/daniel-miller-lifes-playlist/, the guy in the upper left appears to be Daniel Miler himself. He has the same nose, chin, lips, and earlobes, anyway.
My thirty minutes of research hasn't found any more answers than that.
