After reviewing the abysmal interpretation that is available here on UG, I thought 
I'd redo this song for you. Cheers.

Intro D, Bm, G, Em7 

       D                                  
Early morning by the riverside,
        Bm
Saw an old man waiting for a bite,
G                                         Em7
We started talking and he took me back in time.
       
          D
He said I was young, and thought I'd always be,
        Bm
Then I woke up, now I'm 83
           G
There's so much I missed, oh how I wish
            Em7
I could get back all that time I wasted.


Chorus:
D
I see the tears of a young bride
Em7                             G
The morning that we had our first fight.
                    A
I should've held her tight.
D
And on the day that my momma died,
Em7                                G
I hung up the phone and never said goodbye.

Don't let it slip on,
A
Don't let it slip on,
                     D
Don't let it slip on by.


Verse 2
         D
Well, he looked up, tears in his eyes.
Bm
Said I'm not sure if you were looking for advice.
             G                                     Em7
There's just something about you that reminds me of me.

         D
It ain't easy always looking back,
      Bm
But it seems these days that it's all I have.
     G
What hurts me the most is knowing what could have been,
         Em7
And if I listen real close sometimes I can

Chorus
D
Hear the sound of my little boy
Em7                                         G
Saying, daddy can you please come play with me?

              A
But I was too busy.
               D
Then one day, my baby grew up and went to war.
Em7                                             G
I never thought he'd be gone in the blink of an eye.

So don't let it slip on,
A
Don't let it slip on,
                     D
Don't let it slip on by.


Bridge
                      Em7                
I shook the old man's hand and I thanked him.
            D/F#                     G
And I drove home as fast as I could go.
                C            Em
Just to let her know...

D
That I need her,
       Bm
That I love her,
         G                                        A
That I'm never gonna let another moment like this slip on by.
                     D      Em     G      A
Don't let it slip on by.

D
We're only here for a little while,
Em7                           G
And God gives us only so much precious time.

So don't let it slip on,
A
Don't let it slip on,
                     D            Em7
Don't let it slip on by.
                     G            A
Don't let it slip on by.
