Okay, I saw a chord version of the song, played it,
decided it was a little too simplified and mapped it out myself.
It's in standard tuning, it sounds cool in Eb too.  Put a capo on if you want, it's 
regularly played on keytar so be creative with it!
Email me for any feedback, I take critisism well.

Hope this helps.  Too lazy to strum it out, strum it any way you want, like I said, be creative :)

Intro riff, as close to piano as possible, some guitar twists though...
