'Distant Early Warning' was my introduction to Rush, as far as I remember.
(Sorry, can't embed the video, but you can watch it on YouTube's site.)
The 80s-ness of this video is amazing. 2/3 mullets, obsession with the danger of the Cold War (with good reason!) a la Strangelove, funky-shaped bass and drums, skinny tie (Alex), coat sleeves pushed up (Geddy), knees-together dance (a favorite style of mine ;-).
Nevertheless, I think the song holds up really well.
My friend Aaron Retish was the only Rush fan I knew.
(Google says Aaron now teaches Russian/Soviet studies (goes nicely with this video!) at Wayne State University. And he looks about the same!)
I still don't own a Rush album, but the singles I own (via Amazon mp3s) are: Tom Sawyer, Limelight and Distant Early Warning.
My friend, Kurt, hates Geddy Lee's voice, but I think this is unreasonable ;-)
