Jean Knight is best known for her hit, "Mr. Big Stuff." It's one of those situations when you know the song and words, but have no idea who sang it. I discovered this song while watching Superbad. You can hear it during the home ec scene near the beginning of the movie.

It's a pretty funny scene and the song works really well in the context, considering the forwardness of the lyrics. Simply put, this is a good song, old school R&B song, the way they used to make them.

Check out this excellent analysis about the release of the "Do Me" single.
