My Friend John (Lennon)

This is a fan fiction story about a homeschooling girl named Jeanny, who has known a ghost named John for as long as she's known anything. Jeanny likes The Beatles, but her friend, Michelle, is completely obsessed with them. They're both acting in The Tempest, a Shakespeare play, and it's not until the fifth rehearsal that Michelle brings Jeanny to realize who John really is... Let's see if you can guess who John really is.

Note: For people who actually know me in real life, I'm using The Tempest because it's the only Shakespeare play I really know besides Macbeth, and that's because I was just in it.
