California Saga is playing the Ella Awards ceremony with Al and Brian's kids. David Marks will be playing as well. Whatever the rift between the two camps is, it can't really be THAT huge, can it?
It's not "Old Pink Floyd" style hardcore. They work together when they all benefit. 2012 proves that.
As to Mike, I like his singing. He has a voice that is good for what he does. He is the Roger Daltrey of the Beach. Not a great singer but perfect for what he does.
