[VERSE]
B                                      E
Lightning strikes only once in your life
Abm                                         F#
I guess lucky \’cause I\’ve found myself
E
In the line of fire tonight
B                                                        E
My heart beats like thunder under my skin
Abm                                      F#                                      E
And my world speaks in wonder since you appeared
E
Now we are here

[CHORUS]
B                    F#                    Abm
And I could die in your arms tonight
E                                      B
But it would be a shame
F#                                      Abm
\’Cause I want to live a thousand lives
E                                      B
And be your immortal flame

And be your immortal flame (Your immortal)
