The other tab has a few things wrong with it and isn't that detailed. This tab is 99%
- the only thing I am not sure about is the Bminor which seems to have some sort of added
but I can't make it out. The violins make it quite hard to hear the guitar at the end 
I think I nailed it. Enjoy, it's a beautiful song.

[Verse 1:]
You make me faint but you are worth it,
I'll walk you home if you ask it,
Its such a shame thats she never took the blame,
Shes never coming round to me,

[Verse 2:]
You step on your ciggarette,
You right you deserve it,
Who's to blame that shes never coming back?
Shes never coming back,
To me,

[Bridge:]
Please come back around to me before I drown,

[Chorus:]
This is my parting gift for you,
This is my last chance to be true,
Before I get older,
Before you get older,

[Chorus:]
This is my parting gift for you,
This is my last chance to be true,
Before I get older,
Before you get older,

[Chorus (plucked):]
This is my parting gift to you,
This is my last chance to be true,
Before I get older,
Before you get older,
And I drown,
