Since this is seemingly the only record released by "Marjorie Black", I'm gonna go out on a limb and say that Marjorie Black was a pseudonym used only on this record (perhaps it's one of the Soul Sisters, who also recorded on Sue?).
There is simply no way a woman with a voice like this could have only had one shot at recording, unless there was some sort of tragedy (as is the case of Junior McCants who died just as his second record was being released to radio).
"One More Hurt" is one of those records where EVERYTHING clicks; fantastic song, amazing arrangement with a bass guitar intro/ hook (how many times do we hear THAT?) and of course "Marjorie's soaring vocals.
