ohn has had some literal ups and downs since Appleseed issued his "Havana" CD in 2003. A longtime advocate of the US space program, providing music for a 1964 NASA public service film and writing "Armstrong" about the 1970 lunar landing, John was delighted by an invitation to entertain members of the Astronaut Hall of Fame at the Kennedy Space Center during last spring's induction ceremonies of three new members. And, of course, eBay's use of John's "Daydream Believer" has provided a nice infusion of income and interest. On the downside, John is not yet free of the effects of a concussion he sustained while shooting photos at a racetrack two years ago, an accident that has left him with residual vertigo and some difficulty in remembering song lyrics. But he's still touring, still writing, still singing and recording to his own high standards and our own high hopes. He's John Stewart, "a man who hasn't lost his enormous faith in people and who earnestly but eloquently compresses more than four decades of dreams and regrets into his songs" (Rolling Stone).
