I'm familiar with Harold Melvin and the Blue Notes. My favorite of theirs is "The Love I Lost".
That’s a great one too. For a white guy, I deeply prefer 70’s R&B music.
I think both songs have long versions. Pendergrass sang lead on both and really let’s loose.
I’m not real familiar with much of his music, but I think I’m going to listen to more of it.
My favorites are Earth, Wind and Fire and the Spinners.
