Thanks for pointing that out Simon.  That makes it trivial to implement, 
good old Debian :-)
So /etc/network/interfaces for John should now be...
auto lo
iface lo inet loopback
auto mybridge
iface mybridge inet dhcp
   bridge-ports eth0 eth1
Rather simple after all - thanks to everyone who helped me help John ;-)
