I want to know the answer to the following question:
What was the longest that a song spent at #1 on the adult contemporary charts in the 1980s?
All the background I'm provided with is that "Two of these were by Lionel Richie, "You Are" in 1983 and "Hello" in 1984, which also reached #1 on the Hot 100.". Is that enough to answer the question?
Answer: no
