I believe it was a typo. The Don't Forget The Motor City website has the credits as Barnes and Kerr. There is an unreleased acetate of a Norma Jenkins version of the song.
The other big tip off is the acetate itself- look how far the grooves are spread out. I don't have one 60's or 70's (pre -Disco) acetate that has the grooves spread out so far- they are usually the same size as they would be on the 45.
