Hey man. Just checking this thread again after a few months. Wow, I'm sorry but I'm sure by now you know that I made a mistake. The 3rd chord is actually a C#m not Cm. My fault. I guess I was typing too fast all those months ago.

The song is basically E-A-Cm-B and then variations of those chords. Listen to it on Youtube and play those four chords along with it and after a few run throughs you'll get it.
