Revisiting RUSH

This is a live concert intro for The Spirit of Radio that contains many rifs from other RUSH songs.
I did a pretty good job of recognizing them since I've binged on RUSH for decades.
I have 21 of their CDs and 10 different concert DVDs, (yes I counted them), and that's not their entire catalog.
I have never heard more music and sound coming out of just 3 people!

Anyway, here's The Spirit of Radio, live with a long intro.
