There is a member of The Shirelles who sometimes goes by the name [http://musicbrainz.org/artist/497b1bb8-fd3c-4fcd-b32f-736bb8bfe1e6.html|Addie "Micki" Harris]. I haven't found any evidence that that this artist and Addie Harris are the same person. If someone does come across such evidence, these two artists should be merged.
