This was 50p at a boot sale this summer; Candi Staton's self-titled third album.
Candi Staton - Candi Staton (1972)
I can't find a lot of info about this LP, and don't know how successful it was. However it has been released recently on CD along with her other recordings on the Fame label.
The only song available on Spotify is her recording of In The Ghetto, so here it is, as well as a youtube vid of another of my faves from the album:
