Elvis Presley: Return to Sender
It might almost be cliche to post this song since it's such a quintessential mail song, but alas, there are a few oldies but goodies I feel somebody ought to post this week, so I am going to go ahead and post this one to get it out of the way.
This song was a number one single for Elvis. It's a catchy little song that was featured in his film "Girls! Girls! Girls!", about a guy trying to get his lady back by sending her a letter and the letter being returned over and over again with the "return to sender" stamp on it. He finally gets the point when he hand delivers the letter and it still comes back to him. The boy might be a bit dense, but it makes for sweet little tune.
