The song is about a box that is found after Daddy has died. The box holds some things that have meant something to Daddy. I believe it was a Country song. Maybe in the '90's or early 2000's. Thanks I hope this is the song you're thinking about.
"The Box" by Randy Travis
On the top shelf in the closet,
In the workshop where he spent his extra time
Was a dust wooden box that I had never noticed till that time
And we set on the table and carefully, we opened up the top
And stared into the memory
Daddy kept inside the box
There was a letter from mamma, when she went out to Reno
To help her sister out in 62
And a flower from Hawaii, when they went on vacation
It was the first time that my Daddy ever flew
And the pocket knife I gave to him on Fathers day
Years ago, I thought it had been lost
We all thought his heart was made from solid rock
But that was long before we found the box
I guess we always knew it_but "I love you" was hard for him to say
Some men show it easy and some just never seem to find the way
But that night I began to see the softer side of some I had lost
I saw the love he kept inside the first time we opened up the box
There was a picture that was taken,when he and Mom were dating
Standing by his 1944, and the faded leather Bible, he got when he was baptised
I guess no one understood him like the Lord
And the poem that he had written, about his wife and children
The tender words he spoke were quite a shock
We all thought his heart was made of solid rock
But that was long before we found the box
Yes that was long before we found the box wow, sounds very interesting but i can't place it...sorry! Nearest I can think of is Caroll County Accident - Dolly Parton.
