Yeah I have to say I'm confused because I'm pretty sure anyone whose ever listened to Dashboard Confessional has heard "Screaming Infidelities" before. Like, I heard it as an acoustic song from Swiss Army Romance long before I ever heard the one from Places. So that just seems fucking lazy as to me. Still, the Underoath one will be cool as that's my favourite Underoath song. Hopefully it doesn't fall flat and suck like that awful acoustic Alesana song from ages back...
I just listened to Cute Without the E from Punk Goes Acoustic 1 and it's not Fred singing. Definitely John.
