Ok, saw the documentry last night. It was amazing. I think it would probably be interesting for anyone who like music at all, whether you care for Rush or not.

I had no idea how limited a showing it was- I just went to the theater 10 minutes from my house not realizing that it was the only showing in GA- some people drove 7 hours to see this thing! It will be available on DVD in about a month though, and I cannot recommend it enough.
