The version I have is a duet with Justin and Kori from Mates of State. Filled with lots of finger snaps and after the second verse I think you can hear Christian whispering something in the background.

LUCK OF MINE

Now that it's November
we can say our last goodbye
but I can still remember when
you loved me in July
I hope you know it happens all the ti-ime
I just can't seem to shake this luck of mine

So go my little firecracker
brighten up the sky
and on our independence day
I promise not to cry
I hope you know it happens all the ti-ime
I just can't seem to shake this luck of mine

Darling little conflict diamond
confident to cold
why do you feel guilty if you're given
or you're sold
I hope you know it happens all the ti-ime
I just can't seem to shake this luck of mine

Now I must drive fast away
far into the black
and if I live a million years
i'll never once look back
I hope you know it happens all the ti-ime
I just can't seem to shake this luck of mine
