Guitar 2 and lyrics (start as guitar 1 repeats bridge 2 - play continuously and fade out at end)
"I came back...
I came back...

I came back, back
Back to, life
I came back, back
Back to, life


I came back, back
Back to, life
I came back, back
Back to, life

I came back
(I have waited for this day)
I came back, I came back
(I have longed to feel this way)
I came back

I came back
(I have waited for this day)
I came back
(I have longed to feel this way)
I came back

I have waited for this day
To feel I'm fitting in (I came back)
I have longed to feel this way
To be alive again (I came back)
