It was Jon Stewart's 50th birthday yesterday, and he welcomed everyone's favorite model train enthusiast, Neil Young, onto The Daily Show to discuss his new "scattered" (Young's words) autobiography, Waging Heavy Peace. Among other things, they discusses Young's fear of ghostwriters, his positivity, vinyl listening parties, the power of Crazy Horse, and his willingness to self-reflect. And he revealed his curmudgeonly image doesn't really reflect his real personality: "You know, behind the scenes, I'm really nice."

In the extended second part of the interview, he went into more detail about Pono, the portable music player and accompanying high-quality audio service he has been working on (and is due to come out next year). He explained the problem with MP3s: "You lose the soul," Young said. "You lose the feeling, you lose what makes you feel good, what makes music live. If you were Picasso, and you made a Picasso, and then it came out and everybody saw it and it was a Xerox of Picasso? That's what it feels like."

He also tried to describe the crazy chemistry he has with his on-again/off-again backing band Crazy Horse: "I don't know how it happens, but when I'm singing and playing with Crazy Horse, I'm a different guy," he said. "I write a different thing, I see things differently, I see deeper pictures, I'm able to write and express myself much deeper in a certain way that I can't do with anybody else." Young and Crazy Horse are still on tour, will play Barclays Center on December 3rd, Webster Bank Arena in Bridgeport, CT on December 4th, and a Hurricane Sandy benefit on December 6th at the Borgata Casino Resort and Spa in Atlantic City. And Young's new album, Psychedelic Pill, is out, and it's his best album since 1994's Sleeps With Angels. Listen to the sprawling epic "Ramada Inn" and the phased-out title track below.
