As you can imagine, over the years I have been asked many times to discuss and explain my song "American Pie" I have never discussed the lyrics, but have admitted to the Holly reference in the opening stanzas. You will find many interpretations of my lyrics but none of them by me. … Sorry to leave you all on your own like this but long ago I realized that songwriters should make their statements and move on, maintaining a dignified silence.
