About Aretha's UNTIL YOU COME BACK TO ME

[Boogiedown]

I've almost decided that UNTIL YOU COME BACK TO ME [[THAT'S WHAT I'M GONNA DO) is my all-time top favorite song by Aretha Franklin. I find her breezy delivery a wonderful exercise of restraint. She sails through it so seemingly effortlessly.
I knew the song was written by Stevie Wonder , but I was under the impression he'd freshly written it for her at the time. I didn't realize he'd recorded it himself a full six years earlier but the song was shelved and never saw the light of day.
Which begs the question, how did it lay dormant all those years only to eventually wind up in the hands of Aretha Franklin? Does anyone know how that came to be?

Stevie's version was revealed on his LOOKING BACK LP four years after Aretha's #3 version that was recorded in 1973:



I'm hearing it for the first time tonight and I'm finding it terrific, and all the moreso as a 1967 recording.
