Annotation
The Three Degrees began in the early 60s as the original trio of Fayette Pinkney, Shirley Porter, and Linda Turner - but the group underwent many member changes throughout their long history, so keeping track of the lineup changes can be quite a challenge. as far as i could fairly determine, i've added comments to several of the album and compilation groups to indicate the actual lineup in those albums/compilations, though in some cases, the complications extend to recordings by different lineups being included within the same compilations, particularly with boxsets.
