Before It Gets Old: '30 Rock' Benefit Song

So many guest stars! It's sad to see another season of the totally outrageously hilariously awesome 30 Rock end, especially given today's totally outrageously completely lame news that it once again won't start until midseason next year. Blerg indeed.

But savor the good times with this video, from last week's season finale, featuring Clay Aiken sharing the mic with Elvis Costello, a surprisingly relevant "We Are the World" parody, a conspicuously absent MCA, and a bunch of people--like Steve Earle and Rachael Yamagata--that were never identified during the episode and thus a lot of people probably didn't recognize. Sad!
