Beg to differ, it sounds very much like Jerry Williams and nothing like Chris (Marke) Jackson who sang in a very distinctive Eddie Kendricks - like falsetto.
It is well known Jackson had a falling out with Dave Godin at the time.
For what it's worth, there's only one (unsupported) comment on a youtube clip of the track but at least it's unequivocal : Ethan Howarth 1 year ago "This side is actually Jerry (Swamp Dogg) Williams."
Also of some interest is Tim Brown's recollection of a discussion he had with Dave Godin: https://timbrowntalks.blogspot.com.au/2012/01/
Right On!
Manifesto December, 2011
As we enter the final month of a year which on a global scale has seen financial turmoil, I’m bound to report that record sales seem busier than for some time, perhaps it’s like the world of football where money bears little relation to the world outside and what stays within goes around and around. Whatever the truth your money seems safe in vinyl…
A couple of minor points from previous ‘Tim Brown Talks’ cleared up by friends. Neil Rushton informs me that Canada’s stranger-than-strange Right On! Label was a Bill Downs project (ex–manager of the Ad Libs and Jellybeans amongst others) with the approval of Dave Godin (who denied all knowledge of it to me). It still seems a strange set of releases – rich in irony, tainted with plagiarism, almost mocking the Soul Beatnik in fact. In October’s Manifesto I mentioned the demise of the Coaster’s Carl Gardner and speculated that he might be the ‘Crazy Baby’ singer. I should have taken a look at the single which is in fact almost totally a Billy Guy effort. He wrote and produced the record as well as singing it – without the other Coasters! Thanks to Beatin Rhythm’s Derek Howe for pointing that one out.
Staying with October’s Manifesto and Simon White speculates on that odd Chris Jackson Soul City release of ‘I’ll Never Forget You’ with its different flipside to the US Jamie release. Godin told me that Chris and Marke Jackson were different artists, a circumstance supported by ‘Forever I’ll Stay With You’ on the UK issue, but of course ‘I’ll Never Forget You’ is identical. Clearly Godin got around any licensing difficulty by claiming ‘Forget’ to be a re-recording, not wishing to over-egg the situation a different flipside lent a little credibility and they used a different vocalist for it. I think we can safely say that Marke Jackson and Chris Jackson (possibly Chris Bartley too) were the same person (excepting that Soul City flipside). Keep the faith, right on now.
