Rush Fans will tell you, "They are better to go see than to listen to."  I've been present for Rush Performances five times between 1977 and 1981.  I agree with that assessment.  I was deaf in my right Ear for six months due to a welding accident and went to Saginaw, Michigan to see Rush at the end of their Hemispheres Tour that winter.  The Rockets were the Backup Band that night.  Near the end of the show I moved from the floor up to the back center position to get the best sound.  My Ear broke open and drained out and I could here with both ears again.  I was ecstatic.  This composition was one that I could hear properly.  I love it.  They introduced Free Will, Jacob's Ladder, and The Spirit Of Radio after a final Curtain Call.  Sorry to go on so long but I also seem to remember Mr. Lee saying as the Show began, "We're going to do everything tonight", which may be what happened?  These Guys are Top Notch Entertainers.  Oh yeah; I had to wait for more than six months to finally get, Permanent Wave.  My Friends were sick of my promotions of Them by then.  Listen to this without distraction or better yet, go see Rush for yourself.
