Diana Ross - Once In The Morning - Ivo del Prado 12" Version ???

Hi,
on wikipedia they mentioned the 12" Versions of the great Diana album THE BOSS.
They also mentioned a 12" Mix of Once In The Morning:
Ivo Del Prado remixed the bass-heavy "Once in the Morning" which is a very difficult promotional-only to find

Does anyone has some informations about it. I found a YouTube Video with that mix, but for me it didn't sound like 1979. Does anyone knows if there really was a Promo of "Once in the morning" with that remix or is the Ivo Del Prado Remix a new one.
I also found a soundcloud-page of him and on that picture he doesn't look like he was still born in 1979 :)))

THANKS
