This is how Kacey plays it live. She does a few simple hammer-ons in the verses on the Cs. Should be accurate.
Capo 7
[Verse 1]
Em Am C
Do we really have to grow up?
Em Am C
If we never do then so what?
Em
So what if I don't wanna, what If I'm just
Am C
Gonna stay drunk on all the years that I
Em Am C
Just wish would slow up?
[Chorus]
G Bm
We can't do it over
C Am
They say it's now or never and all were
G Bm
Ever gettin' is older
C
Before we get to heaven, baby, let's
Em B7
Give them hell, might as well
Em A
Cause we don't know when we're done
C
So let's love hard, live fast
G Bm C
Die fun
[Verse 2]
Em Am C
Let's put a little more in your glass
Em Am C
Walk around and spend all our cash
Em
Just let me grab my poncho
Am
I don't care where we go
C
If we speak the language you know
Em Am C
We don't even have to come back
[Chorus]
G Bm
We can't do it over
C Am
They say it's now or never and all were
G Bm
Ever gettin' is older
C
Before we get to heaven, baby, let's
Em B7
Give them hell, might as well
Em A
Cause we don't know when we're done
C
So let's love hard, live fast
G Bm C
Die fun
