what to write about, what to write?

I want to write about the Beatles for my free choice essay, for sure. Hopefully. I have it narrowed down to two ideas, but I am open to other options.

• the "Bigger than Jesus" controversy, was the reaction acceptable or blown out of proportion
• the "Paul is Dead" conspiracy, is he or not, the "clues"

I am open to other suggestions too! Thanks in advance for the help.
