First verse:
Bm
We must be shrewd or stupid,
G F#
One of the two,
Bm
The Stakes are too important,
G F#
For us to lose,
Bm
But he would have broke your heart,
G F#
But she would have lead me down the garden,
Bm
They would always leave,
G F#
Early in the morning,
G
No final kiss,
F# G F#
No final warning,
Chorus:
[ Tab from: https://www.guitartabs.cc/tabs/m/milburn/rubicon_tab.html ]
Bm
Just as we're friends today,
G F#
Tomorrow we'll be lovers,
Bm G F#
Never to be the same no more, no more,
Bm
We've crossed the Rubicon,
G F#
And we can't turn our heels,
Bm
So it's onto the breach,
G F#
Oh we'll have to teach ourselves, my love,
2nd Verse:
Bm
And I'll be telling tales,
G F#
If I, claim to be sure,
Bm
That this will last forever,
G F#
Just look at the way it has gone before,
Bm
But he would have broke your heart,
G F#
And she would have taken me for granted,
Bm G F#
They would always leave early in the morning,
G
No final kiss,
F# G F#
No final warning
Chorus:
Bm
Just as we're friends today,
G F#
Tomorrow we'll be lovers,
Bm G F#
Never to be the same no more,
Bm
We've crossed the Rubicon,
G F#
And we can't turn our heels,
Bm
So it's onto the breach,
G F#
Oh we'll have to teach ourselves, my love.
I'm pretty sure that there is another chord within the song but i can't figure it out.
melody line played by the lead guitar in the second chorus is similar to the intro but
a different ending which i haven't worked out yet.
