Does this song sound natural?

I've mashed together two songs here and I can't decide if it works or not. I've played it better than this (Its 1:30 AM, cut me some slack), and I need a pop filter on my mic, but I'm really just wondering if you guys think this sounds like a naturally flowing single piece of music, flaws in recording aside. If you do know either song, just try to pretend that you don't.
 
And Christ aren't I demanding this morning...
 
Thanks guys :)
 
EDIT: oh yes, the reason I'm doing this now is that I'm playing somewhere tomorrow and am conflicted about whether to play the original song or the combined version.
 
Song = here

it sounded like natural in some parts and others parts didn't. i only listened to about a minute of it.

" @EvilTwin:  The image that I have in my mind of your "oh Jesus Christ that's what it is" moment cannot possibly be as entertaining as the real thing :)  Hmm, thanks I suppose. I'm still not really sure what to do then. I'll probably just stick to the original. That way nobody in the audience will have any way at all to relate to it, which is always nice. "

Sounds 'aight. Originals are better though.

I always skipped over this track on OK Computer so I don't know if its a cover. Regardless, you've got a decent sound. Try and project your voice more. We already have tons of Folk-y singers with whisper voices, set yourself apart from the pack, bro!

All the indy kids will be way into it.
