In 1988, Deniece Williams made a final trip to the Hot 100 (#66) and the R&B top 10 (#8) with "I Can't Wait". I truly don't know why this wasn't a bigger hit. I know there were stations playing this at the time because I have an aircheck of Power 106 in LA playing it. Of course, you'd never, ever hear this on good old Bob FM (slogan: "we play anything"). I suppose Jammin 105.9 might be the likeliest candidate to play it, but since they seem to be transitioning to a hip-hop format, I guess that ship's sailed as well.
Edit June 2010: The imeem widget with this song has disappeared (thanks a bunch, MySpace), but I did find the song on YouTube. (She's lip-syncing here...this is the studio version.) Check out the cool 1988 fashions!
