I don't think
Sadie and

I think a two syllable MN with the emphasis on the second syllable (

If heaven and hell decide that they both are satisfied
Illuminate the 'NO's on their vacancy signs
If there's no one beside you when your sould embarks
Then I'll follow you into the dark..~Death Cab For Cutie
