Not only the higher notes strain, but so much of that song is taken up with his theatrical storytelling/British Pathé newsreel voice. I love it, and it fits the song beautifully, but it doesn't demonstrate the heights of his vocal ability.
I struggle to isolate just a couple of lines from anything. Most of Jerusalem is pretty magical.
"Let it rain
Let it rain
Tears of blood fall out of the sky"
Two songs that jump to mind straight away, although they're not covering all of Bruce's vocal scope either, are Moonchild and Infinite Dreams. I love what he puts into those. He uses a different vocal style for the Devil character in Moonchild and throws loads of dramatic effect into it. Infinite Dreams is more his 'normal' voice for the beleagured human character, and has such passion in it.
I'm quite fond of the passion he throws into Ghost of the Navigator too:
"I steer between the crashing rocks, the sirens call my name
Lash my hands onto the helm, blood surging with the strain"
