Jr Ross/Frankie Jones/ Palm Trees question

[flashman]

Someone please refresh my memory here. I recently picked up the Step It Out 7" by The Palm Trees on Hawkeye. I heard the clip on Ernie B and recognized it as ( I thought) a different version of a tune I knew or had by Jr. Ross. I mean, for some reason I thought this was maybe an earlier version credited to Palm Trees. I know Palm Trees is Palmer brothers, which includes Jr Ross and Frankie Jones.
I also associated it with the Frankie Jones tune Step Outta Babylon on Satta an Praise Jah: different riddim, same tune/lyrics.

The weird thing is that I now can't remember where I originally heard this tune. I assumed I knew it from the B&F comp, but now I see it's not on that.

So my question is: Is there another Jr Ross version of Step it Out that is different than the Palm Trees version? There has to be or else I wouldn't have recognized the tune from the EB clip, but I can't place it now.
