This song had to come out in the late 80's or early 90's; it was a male group, and some of the lyrics are:
(Chorus) It's on baby tonight, it's on baby tonight, everything's gonna be alright
(Lyrics)
Don't forget what we said when we're finally alone; don't pick up that phone
turn the lights down low, move our bodies nice and slow
don't interfere

sounds like a younger male group but I can't find anything online; been looking for over a year. Please help if you know anything about this track! I have it on cassette and if I find it and get more lyrics I will post them. Had to come out around the same time as Force MD's "Love is a House".
