The highest note in "Circumstances" is a D5
The highest note in "Freewill" is an F5
The highest note in "Available Light" is a D5
The highest note in "No One at the Bridge" is a G5
The highest note in "Cygnus X-1" is an A#/Bb5
The highest note in "2112" is a G5
The highest note in "Marathon" is a C5 (I think...I'm not positive, I'll have to go back and listen again)
The highest note in "Anthem" is an E5
The highest note in "Bastille Day" is an E5
The highest note in "Finding My Way" is an E5
The highest note in "Fly By Night" is an F#/Gb5
So there's your definate answer, coming from a guy with perfect pitch. As per OP's request, I used only studio recordings for this.
I make the high notes in Marathon C#, which Geddy also reaches in Red Barchetta, and I believe Secret Touch from Vapor Trails.
I think that Geddy's highest note on Snakes & Arrows is B(4?) which he sings in Far Cry. Any others?
