Capo 1st

Intro 2x : G, D (slide B&E string up to 5th fret),Cadd9   

   G
I remember looking up 
             Cadd9
To look up to him 
G
And I remember most the time 
         Cadd9
He wasn't there 
       Em7            D
I'd be waiting at the door 
                    Cadd9
When he got home at night 
      Am                  Em7             D
He'd pass me by to go to pass out in his chair

Chorus:

And I'd say 
G                 Em7
Walk a little straighter daddy 
Cadd9                  D
You're swaying side to side 
G                         Em7
You're footsteps make me dizzy 
Cadd9                D
And no matter how I try 
          Am          Em7
I keep tripping and stumbling 
Cadd9
If you'd look down here you'd see 
                Am         Em7    D
Walk a little straighter daddy 

You're leading me

Intro 1x

He stumbled in the gym 
On graduation day 
And I couldn't help but feel 
So ashamed 
And I wasn't surprised a bit 
When he didn't stay 
He stumbled out before they called my name

Chorus:
And I thought 
Walk a little straighter daddy 
You're swaying side to side 
It's not just me who's watching 
you've caught everybody's eye 
And you're tripping and stumbling 
and even though I've turned 18 
Walk a little straighter daddy 
You're still leading me

G

Bridge:
F
The old mans still like he always was 
     Em7
But I love him anyway 
         Am
If I've learned one thing from him 
                 C             D
Its my kids will never have to say

Walk a little straighter daddy 
You're swaying side to side 
You're footsteps make me dizzy 
And no matter how I try 
I keep tripping and stumbling 
if you'd look down here you'd see 
Walk a little straighter daddy 
You're leading me

Yeah walk a little straighter daddy 
You're leading me
