Neil Young likely used various means of travel to arrive on The Colbert Report set last night to talk to Stephen about cars, the Pono music player and protecting the environment. Since Neil didn’t get famous by sitting around and talking, the legendary rock star did what he does best by standing up and trying to save the Earth through song by singing a song called "Who's Gonna Stand Up? (and Save the Earth)" with the help of the musically inclined Colbert. Despite their differing environmental views (Young would like to stop fracking while Colbert thinks we should start fracking whales), the duo pull off a very lovely performance that you can watch now instead of doing whatever it was you were going do before you noticed this post.
