any word on who the new drummer will be?

Jason Bohnam (John's son) will be on drums.  I have seen his band The Jason Bohnam Band twice.  They were basically a Zep tribute band with a few of their own tunes.  The boy doesn't miss a beat. He is a hell of a drummer, but how could he not be when his dad taught him how to play.  I think it is the best choice for drummer and have been hoping this would happen with this lineup for years!  Jason is currently the drummer for Foreigner and they are playing this show also.
