Well, I love all their stuff, but I'm sure just as with any other band you like, it seems that their most popular songs tend to be the "weakest" tracks on the album. Then again, Rush does have a lot of lengthy tunes, so it would stand to reason why some of those songs don't turn up on the radio. It isn't that they aren't good...just very long.
Yes, Beyond the Lighted Stage is a great DVD. Glad to see that the "mainstream" is finally giving them the respect they deserve.
