I know some lyrics, but don't know who sings the song or title. The lyrics go something like this " you don't have to say a word, I can see it in your eyes..." It's a R & B song. I want to say it came out sometime in the 90's.

Was it a group or solo artist? Male or female?

It was a male group.

Maybe it's "Written all over you face" by the Rude Boys...
