I still think that it's just Jon and Shanks at the mo putting the basics together. I douby any of the other band members are involved at this stage. The fact that they are still writing suggets the the band recording sessions are still a way off.

of course it could also be that Jon and Shanks are in the studio doing some overdubs for the box set? We know that overdubbed on the last box set and Burning Bridges don't we?
