Same sort of thing as to why Maiden don't credit other songwriters who actually are co-authors of their songs. Only members of Iron Maiden should play or write on an Iron Maiden studio album.Bruce didn't have to play the part simply because he wrote it.
As to the vocals... I can't stand them sometimes. Bruce should maybe consider not trying to sing as high as he used to. It doesn't sound nice, and hasn't since Dance of Death, if not earlier.

Edit: Although, they do credit orchestration work.
I’ve said it before but as long as Steve Harris is at the helm, it doesn’t really matter who the producer is. I imagine a more hands on producer like Sneap or Roy Z would fight Steve’s wishes until finding themselves out of a job. Then you have an album produced by Steve without any other input.
Shirley is the best guy for the job. He knows the band as musical personalities and is able to make really good sounding albums with minimal processing (see Counterparts by Rush). If Steve would stay out of his way, we’d have more albums like Brave New World, which is one of the best sounding modern metal albums.
The overall sound, guitars above all, on the intros of tracks like "When The River Runs Deep" or "Shadows Of The Valley" is truly embarassing for a band like Maiden (the cases are many on this record, I've just named a couple...).
Another thing that factors into this is that on AMOLAD, Steve specifically requested Nicko be a bit more laid back rather than flashy. I'd argue that while the songwriting clearly doesn't allow him to do what he did in the 80s (where practically every song had its own unique beat or bag of tricks and Nicko almost never played anything even approximating a straight rock beat), he definitely was quite a bit more adventurous on BNW and DoD - the latter especially - than he is on the albums from AMOLAD onward.Well, I do like the sound on that record way more than on the previous one or the one that followed. Nicko's drumming can't be matched, but I feel that from 1990 on, it's because of the way the songs are written, the structures. They're more tight. There's less room for him to go crazy like, for example, on The Loneliness of the Long Distance Runner or Deja-Vu. I mean, ask any drummer, on these two songs his performance is just unbelievable. He should have gotten song writing credits. If they had any other drummer record these songs, they would sound less unique.
