Well I met Sierra at the casino bar,
E5                                                 E5
And she said, "I have travelled on my way too far"
E5                                   E5
Well hey Sierra, let me pick up your tab,
E5                                                             E5
She said, "I got something to tell you boy, just don't get mad,
A5
And I hate saying this but it was so much fun,
E5
Oh I killed a woman back in 1991"
