Personally, my theory is that Rock Candy only ever recorded ONE track, and that was "I Don't Think I'll Ever Love Another". My guess is that Joe Tate, or whoever was in charge of Dontee, needed a B-side filler on this occasion. Thus, "Alone With No Love" by The Contemplations was used, but still credited to Rock Candy just to maintain consistency.
The two groups on either side sound as alike as the proverbial chalk and cheese.
