I've just compared the album track to the 70s 45 I think the single mix is mono or dubbed from the album it doesn't seem to have the 'depth' of the lp track?
Two other great recordings for ABC were Watch Where You're Going & Loving You, Wanting You, Needing You released back to back under the production of Lamont Dozier pity these weren't on the album.
IMHO ABC were responsible for a lot of quality soulful albums during that period of the 70s Angelo Bond , Nolan Porter (licensed Lizard album),Natural Four, Wilson Williams,The Nights,Chuck Jackson,Lamont Dozier & Al Hudson.
Feel free to add to the list.
