I want to know the answer to the following question:
Did the FBI keep files on Elvis Presley?
All the background I'm provided with is that "The FBI has maintained files on numerous people, including celebrities such as Elvis Presley, Frank Sinatra, John Denver, John Lennon, Jane Fonda, Groucho Marx, Charlie Chaplin, the band MC5, Lou Costello, Sonny Bono, Bob Dylan, Michael Jackson, and Mickey Mantle.". Is that enough to answer the question?
Answer: yes
