Standard tuning but the whole thing tuned WAY down (put 
capo on at 4th fret, then tune so it sounds at normal 
pitch, then take the capo off.) 

The intro chord is described as 'x' below. 

At the rising of the (Em) dove
When the (x) dark betrayal (Em) fails
I'll wake (D) up in love
Where my (C) heart has lain (x) again

On the morning of the (Em) day
When you (x) bring your things to (Em) stay
Heaven (D) will pay
They'll be (C) no more pain (x) again.

I (D) wanna be in love
I wanna be in love
I (C) want to be in love
I (D) wanna be in love
I wanna be in love
I (C) want to be in love with (F*) you (fiddly bit! - see 
below)
In (F*) love with you (Em) (x)
