Elmore Morris, a cousin of BB King, was one half of Double Soul; the other half was Charles Cooper. As a duo they released only one single on Minaret. Both artists released more recordings of their own. Charles Cooper in another duo: Chuck and Mariann.
I agree with Sir Shambling that It seemed Like Heaven To Me (CrackerJack, 1962) is most likely Elmore’s best solo effort. To listen to more of his material please go here.
Sorry. There’s no pic. of the man — but his voice definitely makes up for it.
