I'd never in a million years say that Doni Burdick was a better singer than Edwin Starr, but like I said, the arrangement, production and vocal nuances in the Burdick version are far better than Edwins...for instance, the first line "I was told the other day, go on and leave you", the intonation is far better one one more than it is the other...it's like I was reading this nobhead writing about the classical influences on Beatles tracks and he pointed out that certain chord changes affect your brain differently to others so if for instance someone sings a note going up as opposed to down, that would register more positively with you. Which basically means, on certain bits, Burdick sings these up notes while Edwin sings them downwards and I have to say hand on heart, Burdick puts a lot more into his vocal than Edwin does on this particular...listen to the part "I said don't say it any more, cos I feel like I did before", the one showing the emotion is Doni not Edwin.
