"It's Rough Out There" looked like a glorious Parkway (P-100) one-off for Jerry Jackson: in my view one of the great voices of the 1960s. This interview makes it clear that P129 "Hurry Sundown" and P142 "Pretty Girl" are also his work, though he uses the name Jaxon/Jackson Reese in an attempt to grab that elusive hit.

Once you listen to the records it becomes obvious that it's Jerry's voice, though I can't find any mention of it before. Neither have the same Northern impact of "It's Rough Out There" and sound out of date for 1967. I still love them all the same.
The interview makes no mention of "Take Over Now", released on Capitol the next year by Jerry Jackson. Listening to this one again I'm pretty sure it's a different singer but happy to be corrected.
