Oh Brother

A brother suing a brother because of bad things one said about the other.  Oh, those wacky Gallagher bros.  Oasis were in a creative down spiral anyway, so breaking up now is no big loss.
But the history of Brother acts getting on each other's nerves is a long one.
You've got the Everly Brothers, the Davies of the Kinks, the Fogerty's and how about the latest ones, the brothers of Kings of Leon.  And the tragedy of the Troutman brothers from Zapp.


What's with these brother acts?
