On the third track, it would seem that he is playing 2 tracks (one is a drum track).

I can tell you that the main track (Shined on Me, Someday the Sun Will Shine on Me) is in fact:

Cast of Thousands feat Mimi Johnson - The Sun Will Shine (Marc Pomeroy Mix)

As far as I'm aware this version was not released officially but is available on the following CD mixed by Victor Simonelli:

Various - Bassline - The Comp'
