Our favorite jingle guy is at it again. Jonathan Mann, who TechCrunch readers will best know as the guy behind the awful Bing jingle, has released another new video (as he does every day), this time to serenade the children of Keith Valley Middle School who recently performed his Bing jingle. "It's kind of creepy," Mann admitted at the time, but he was happy to see his work live on, so he came up with this gem.But this latest video almost had a very different tone. "I thought about writing them an anti-corporate anthem, something they could raise their tiny, furious fists to, but ultimately decided on this," Mann tells us. Too bad, because that would be been awesome. It could have been "Another Brick In The Wall " for the 21st Century.
