This song is called "Mailman Bring Me No More Blues" and it is a Buddy Holly song made by him back in 1721 back when cars were in black & white and the wheel was still square. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Mailman, bring me no more blues Mailman, bring me no more blues One little letter is all I can use - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - That's it!
