THIS IS NOT THE SONG YOU WERE LOOKING FOR.
But here is a bit of the one that Sorcha found
from what i can hear of it...

JESUS WAS A COWBOY
by JAMIE GAZELLE

Jesus was a cowboy
He rode that Israel range
He taught us how to love and pray
But some folks said he was so strange

Jesus never carried no guns
His word was a sword
He got him a posse of 12 good men
And he set out to save the world

With heaven as a reward
He's roped my soul
He's branded my heart
