This is the Last Gospel, well at least for the moment. These two screeching preachers are featured on a compilation called "Screaming Gospel Holy Rollers Volume 2". We will return when I've tracked down Volume 1.
"I Must Live Until Morning" - Charles Taylor & The Charles Taylor Singers
"All Over Me" - Reverend Crum & His Mighty Golden Keys
And here is some slightly less sacred screaming.
