Return To Sender Elvis Presley (#2 in 1962)

I gave a letter to the postman, he put it his sack.
But in early next morning, he brought my letter back.
She wrote upon it:
    Return to sender, address unknown.
    No such number, no such zone.

We had a quarrel, a lover's spat
I write I'm sorry but my letter keeps coming back.
So then I dropped it in the mailbox and sent it special D.
But in early next morning it came right back to me.
She wrote upon it:
This time I'm gonna take it myself and put it right in her hand.
And if it comes back the very next day
Then I'll understand the writing on it
