He might, then again he might not. We don't know what he might or might not think because as far as I'm aware he's never said anything about it. It's just speculating based on a caricature of Steve's personality.Y’all don’t think Steve Harris, Mr. “The Mel-Oh-Dee-Goes-Ex-Act-Ly-Like-Thiiiiiiis” would take contention to changing tunings? “The melody isn’t in C#, it’s in D, boys!”
In fact the only anecdote I can ever remember about Steve and changing the keys of songs was related to Cross Eyed Mary. Bruce wasn't in the studio when it was recorded so Steve rang him up to see if he was happy singing it in the key they used or if he wanted to change the key.
