[Gruberama]

This is a fairly (or seemingly) simple song. I just can't manage to pick out the chords. The way I hear it, it seems to go:

D# / C / A# / ?? beyond that I'm not so sure...

You can listen to the song here ( http://www.chimehost.../08-Adeline.mp3 ) Any help would be greatly appreciated. I've looked for existing tabs to this song for some time, with no success. Thanks in advance.
