[Verse 1]
Deliver the letter the sooner the better
The upside down stamp meant the kisses were wetter
I.S.Y.I.M.D., I'll see you in my dreams, honey
T.S., T.S., T.S.A., S.W.A.K. 
X's and O's, who knows what all of that means?

[Verse 2]
P.P.D.S.P.E.M.R.M.F.O.B.T. must have took lots of hours for you to see
What I was saying back then when we were still green
P.M.P.M.D.S.O.F.'s not hard at all
Please Mr. post man, don't stumble or fall
I still remember what M.B.D.D.F.C. means

[Verse 3]
S.W.P.A.P. was a twister, sprinkled with powder and perfume
My sister took two days to figure out
Sweet dreams, forever sweet dreams
S.D.F.S.D. had her seeing double
The envelope looked like a good Chinese puzzle
Yes, I got those letters you wrote me when we were fifteen

[Instrumental Break]
My youngest son
And the oldest son
[Verse 1]
Deliver the letter the sooner the better
The upside down stamp meant the kisses were wetter
I.S.Y.I.M.D., I'll see you in my dreams
T.S., T.S., T.S.A., S.W.A.K. 
X's and O's, who knows what all of that means?

[Verse 2]
P.P.D.S.P.E.M.R.M.F.O.B.T. must have took lots of hours for you to see
What I was saying back then when we were still green
P.M.P.M.D.S.O.F.'s not hard at all
Please Mr. post man, don't stumble or fall
I still remember what M.B.D.D.F.C. means

[Verse 3]
S.W.P.A.P. was a twister, sprinkled with powder and perfume
My sister took two days to figure out
Sweet dreams, forever sweet dreams
S.D.F.S.D. had her seeing double
The envelope looked like a good Chinese puzzle
Yes, I got those letters you wrote me when we were fifteen

[Instrumental Break]
Miles
Oh, swell
[Outro]
Deliver the letter the sooner the better
The upside down stamp meant the kisses were wetter
I.S.Y.I.M.D., I'll see you in my dreams
T.S., T.S., T.S.A., S.W.—
