The Secret Song


My dear John.
I hope your most recent time jump went well.
I've been thinking a lot about the secret song lately.
How am I going to know it's the right song?
Will I hear it randomly on the radio in a certain number of years?
Will it be 100% as you told me?
What if it's not as I expected?
What if I miss it?
I will do my best, I promise.
