50% of their sound if not more ??? Come on. I don't want to look rude, but sadness alters your mind. What about the bass sound, Davey's tone and Bruce's voice ? More importantly, the guy does not write songs, which means that a good drummer will be able to replicate his parts, and certainly with more power and consistance. I hope a new addition will have the same effect Faulkner's arrival had for Priest or Bruce's cancer for Maiden: a big boost. I appreciate Nicko, but he has never been Maiden's best drummer and changes are often welcome.
