Thanks for posting, great interview and the book explains why he was over in London i bet.
Couple months ago, I was walking my dog in Hyde park. Crossing the serpentine bridge, no one was around.
A couple were walking towards me and as they get closer I start to realise it's Geddy Lee. I grew up in USA, saw Rush, 1980 Wings stadium, Kalamazoo Michigan, I was sent there and 2112 was like my only friend in a small town where I absolutely did not fit in .
In other words Rush was a big part of my youth, figuring out how to play all their songs helped me to learn how to play .
I was so dumbstruck, it did not compute, like a weird dream where crazy random characters show up out of context. They stopped and were watching and pointing out birds in the lake, Geddy was sneezing cause the allergies here i guess.
I did turn around and walk past them again on the opposite side, maybe to confirm it was actually him, but did not want to disturb them, it was their private time and they reminded me of me and my wife enjoying each others company and nature,
-no way was I going to bother them.
As they got to the other side of the bridge I crossed back over, and in passing said "thank you " Just as he suddenly sneezed again, so either he was thanking me for being a fan or that i said bless you, and replied as such - anyway I'm good, worst case i can say I blessed Geddy lee.
