Yep, if Plant won't do it, someone else can.
lt's easier to find a decent singer to replace him, than finding replacements for Jimmy Page, John Paul Jones. Jason Bonham can do a great job on drums....
Plant can only sing, he's not a master of an instrument like Page and Jones....
Plant needs to drop the "*****" attitude and get over himself, maybe think of all of the fans that were too young to see them back in the day and would like to see them now....
They could use one of the Foo Fighters to sing also, here they each alternate singing and playing drums with Jimmy Page and John Paul Jones:
