Ha ha, yup, I did. I was walking in a park today and i just got the odd thought of writing it. And so I did. Lyrics to Bring it On (Aliens):

Intro
Em C x2

Verse 1
Em C

We can't keep ourselves away
We can't live that far away
And we can't escape the pain for all of us
Bring it on then, bring it on. Bring it on then, bring it on.

Bridge
G5 C5 A5 Ab5 x8

Chorus 1
G5 C5 D5 A5

There is no reason to be afraid
We Will do, harm.
We come in peace, as you come in pieces
Bring it on then, bring it on, we say, bring it on then, bring it on

Short Interlude
G5 G#5 F5 x2

Chorus 2
G5 C5 D5 A5 x2

End on A5 just make up any strumming pattern until my Youtube lets me show you how and allows me to upload the song. For now, this is the best representation of it i can do. Hope you enjoy

well let me take a stab at this one. well the idea was there
but i don't see my species being taken out by aliens or a zombie apocalypse
all though i do feel that those days may be coming soon
i see us con questing through other worlds once we milk this one dry

so it should be a victory song and unlike the movie avatar this time we will
win humans 1 aliens 0

roll out
