Led Zeppelin were RP, JP, JPJ and JHB as everyone here knows. You couldn't better or improve on that. However technically and skillwise I think there's little difference between them...Jason is his fathers son. IMO Page, Plant and Jones could only play/reform under the name 'Led Zeppelin' with Jason Bonham as the fourth member. He has 50% of his DNA from John Bonham, therefore Led Zeppelin retain 87.5% of their original DNA....and you can't get better than that...Perfick.
Any other drummer and I would have prefered to see them reform under 'Plant, Page and Jones', or a new band name.
