Sledge actually recorded two versions of it, one at Rick Hall’s FAME Studios at Muscle Shoals, the other at Ivy’s own Norala Studios. After recording the first version, Jerry Wexler at Atlantic Records said the horns were out of tune and asked Sledge for a do-over, so they got different horn players and gave it another go. In the end, though, the two tapes somehow ended up being mixed up, and Atlantic put out the first version.

I got it off iTunes … and the lead vocal is different… It's a different performance, really stiff and honky sounding, nowhere near as cool as the original. ... WTF happened to the original tune? … Also the mix is kind of modernized I think, sounds weird. Miss the old one. ... How could you f**k with this song? It was perfection to me.
