I saw Rush at the Omni (Atlanta) for the 'Signals' tour. The next day I was at Peachtree DeKalb airport for my 11th hour of flight instruction and I was sitting on the runway and my instructor nudged me to find out why I did not start the take off roll. I told him I did not hear the tower and it was because my ears were still ringing. That was the last concert where I did not use hearing protection.
