Nancy Sinatra - Bang Bang (My Baby Shot Me Down)

I was five and he was six
We rode on horses made of sticks
He wore black and I wore white
He would always win the fight

Chorus:
Bang bang, I hit the ground
Bang bang, that awful sound
Bang bang, my baby shot me down.

Seasons came and changed the time
And I grew up, I called him mine
He would always laugh and say
"Remember when we used to play?"

(Repeat chorus)

Now he's gone, I don't know why
And till this day, sometimes I cry
He didn't even say goodbye
He didn't take the time to lie.

This is the opening song in Kill Bill Volume I, by the way...
