Neil Young answers fans' questions on Twitter Though an old hippie at heart, Neil Young has made no secret of his interest in technology and gadgets, evident in his passion for vintage cars, trains, cutting-edge audio equipment and, most recently, Twitter. Young signed on to the Twitterverse late in September in large part to help promote his new album with Crazy Horse, "Psychedelic Pill," which comes out Oct. 30. Today he engaged in a live Q&A session with fans on Twitter's recently instituted feature "LegendsOnTwitter," and Young seems to be enjoying himself. After a less-than-scintillating first exchange (Question: "Is that an old Firebird pickup in your Les Paul?" Young: "Yes") the two-time Rock and Roll Hall of Fame inductee started kicking things up a notch. Another fan asked, "When will we get a remastered "Time Fades Away"?" referring to Young's 1973 album, and the artist answered, "When PONO comes out," plugging the new audiophile-quality music playback system he's developing, which he also touts repeatedly in his new book, "Waging Heavy Peace." Responding to a fan who asked "What is the one car you absolutely want to own?" Young said "The Volkswagen levitating car." He cites Foster the People as one of the newer generation bands he admires, and when a questioner noted that "Bono said he likes them too . . . it is surprising two super stars like them," Young replied, "Who is Bono?" Another memorable moment came as a fan begged Young to explain "why is 'Harvest' the only album (and almost only thing at all) that makes me cry?" Young replied, "because you're a sad bastard."
