Fill in the blanks in the lyrics of the song:

[Verse 1]

I wrote a letter to the postman

He put it in his sack

Bright and early next morning

He sent my letter back

[Chorus]

(She sent upon it)

We had a quarrel

[Verse 2]

So then I put it in the mail box

And sent it special D

It came right back to me

[Chorus]

(She sent upon it)
