Piano part translated into guitar. Great song, great Band!
Main Bit: Repeated through most of the song, if you want to you can throughout all of it.
Pattern might be slightly off but 99.9% certain they're the right notes :)

Those are the basics, strumming pattern for "verse" or whatever you wish to call it is
fairly simple and easy to hear chord changes in song.
