Great song, and very simple to play.
Capo 3
Standard Tuning

Intro: Am Em F Em

Am                   Em
Suspicion came from around the bend
     F                    C
and it tapped me on the shoulder
Am                      Em
I heed your warning but I'm sorry friend
F                      C
this is exactly what I want
Am                     Em
Walking in knowingly I have got to get a hold of me
F                             C
This party might be out of my league
Am                      Em
Suspicion stabbed me in the back again
F                                      C
I poured my heart out and I started to leave

CHORUS:
                            F
And all the sudden I can't let it go
                            C
I say we should have gone to Mexico
                        G                             F
You've got love like a fire- though I can't put you out,
                   Am
I can't stand and admire it
                            F
'Cause if I'm with you than I want to be
                            C
So sweetheart take a little drive with me
                        G                          F
We'll get lost in the sun, oh the night's just begun
                  Am
down in beautiful Mexico

REPEAT CHORDS FROM FIRST VERSE:

My feels caught on a spiderweb
as I was walking out and into the desert
I left my heart but somehow kept my head
And I've been acting like I don't even care
But with a drink or two,
like the one I never had with you
I'm slurring all the things that you are
Thinking about what we could have been
And no, I never even make it to the car

REPEAT CHORUS CHORDS

And all the sudden I can't let you go
I say we should have gone to Mexico
You've got love like a fire- though I can't put you out,
I can't stand and admire it
'Cause if I'm with you than I want to be
So sweetheart take a little drive with me
We'll get lost in the sun, oh the night's just begun
down in beautiful Mexico

PLAY THE INTRO THROUGH HORN AND GUITAR SOLOS

And all the sudden I can't let you go
I say we should have gone to Mexico
You've got love like a fire- though I can't put you out,
I can't stand and admire it
'Cause if I'm with you than I want to be
So sweetheart take a little drive with me
We'll get lost in the sun, oh the night's just begun
down in beautiful Mexico
