Paul Young - "Oh Girl"

In short, the recipe for every Adult Contemporary hit song includes one or more of the following:

• A remake of an old song (preferably from the Motown era)
• A British singer (preferably Rod Stewart)
• Use of the saxophone (this rule was mandatory during the 1980s)
• A song that radio station Program Directors deem as "safe" for soccer moms 
• The song should be a ballad

In this instance, Paul Young takes a cue from Rod Stewart, Michael McDonald, and Hall & Oates for his take of the Chi-Lite's classic "Oh Girl".  The song went to (you guessed it!) #1 on the Adult Contemporary chart in 1990.
