I've played the other versions of dream brother on this site and I think the basics are 
but I think the intro goes more like this.  Not meaning to take any credit from the 
tabs. (Apologies if I'm way off the mark, this is my first go at a tab).

Tuning: Standard.

No capo.

Sort of swap between these two and play around with the plucking in a way you feel 
right.  The rest of the song is right in the other tabs I believe.
