Steve Harris is the backbone of Iron Maiden. All things in the band go through him, and it’s been that way since they were founded back in 1975.
In the ’90s the band went through a period of turmoil that saw a new lead singer with Blaze Bayley replacing Bruce Dickinson, and a downturn in record sales and popularity.
Bruce Dickinson has a one-of-a-kind vocal range, and all the Iron Maiden songs before were tuned to his voice.
When Blaze Bayley came into the band, they didn’t tune the instruments down to fit Bayley’s vocal style.
This is one of the reasons why people say that Blaze didn’t end up working in the band. He had to strain his voice to fit the tuning, and it cost them, forcing cancelations on tour.
That somewhat answers the question, it just didn’t come up for the band.
The most important thing about this quote however, is the final portion. Steve Harris recognizes that Blaze Bayley helped shepherd the band through one of the worst times in their history.
It sounds like Harris has a high level of respect for Blaze and his work in Iron Maiden.
