QotD: The Audience Goes Wild

What's your favorite song to sing karaoke-style?  If you don't have one, why not?

I've never done it, but I would love to do "Hemispheres" by Rush. This eighteen minute and eight second progotastic orgy of lyrical and musical self-indulgence, represents a high-water mark in a certain kind of 70s pretension, even more than Pink Floyd "Animals" or Yes "Tales of Topographic Ocean." It explains why the hell punk rock emerged and what exactly they were so angry about.

Doing this song Karoake style would be gauranteed to clear the room because not only is it nearly twenty minutes long, and require you to attempt to reach Geddy Lee's (described famously by a Rolling Stone reviewer as sounding like "Donald Duck booting crystal meth") upper ranges, but it much of the song consists of long instrumental passages during which I would play air bass, drums and guitar, often at the same time. It would be an event of legendary proportions, a "can't bear to watch/can't look away" kind of thing. It might signal the end of western civilization, and the beginning of another. It might be posted on Vox with the tag "whytheyhateus." It might cause YouTube to be able to buy ABC/Disney. It might not.
