If Madonna was the pop charts’ “It girl” of the mid-80s, then Olivia Newton-John had to have had that role in the late 70s and early 80s.* With the release of Grease, Olivia Newton-John’s fame vaulted into the stratosphere. During that period, her music was found on pretty much every top 40 station and almost every adult contemporary station as well. Some of those hits still get some airplay (particularly the songs from Grease), but others are long forgotten. For example, Ms. Newton-John’s top 20 hit “Deeper Than the Night” hasn’t been heard in terrestrial radio in some time.
