Okay, so the story is this: Jonathan Coulton, musician for the people, worked with Quick Stop Entertainment to do a remix contest for his song, "Code Monkey." Kristen Shirts won for having the most original approach, that was not only eminently listenable...but she got bonus points for her use of a ukulele. You can hear her version (and others) here.
Just a couple of days ago, Kristen joined Jonathan onstage for a live version of the remix. Below the break, you can also find the two of them performing "Tom Cruise Crazy" as well. Awesome.
