I have no idea,sorry,the only information that i could find is from the northernsouldirect site
They say:
This is a collector special Just 500 copies have been manufactured on a "white demo" replica of the Detroit HIB label. Inferno are keeping quiet about the identity of the artist, and these copies just credit it to The Illusions. Future pressings will reveal the full information about who has written, produced and sung the track -- so these first 500 are sure to be in-demand collectors’ items. Grab 'em while you can.
The backing track is sampled from Luther Ingram Orchestra's "Exus Trek", one of the truly great Northern Soul instrumentals. Inferno own the master recording and the HIB label which "Exus Trek" was released on - by arrangement with Detroit producer Robert Bateman - and have come up with a brilliant female vocal on an infectiously catchy new song with sing-along chorus which caused mayhem on Rare Soul dance floors.
The single itself plays loud and clear,it is an excellent recording
