"The tour is about inspiring people to make space in their own hearts for peace," says Carlsbad musician Jerry Leggett, who is touring the U.S. in a yellow teardrop-shaped trailer he calls the Peace Bubble.

"I just set up the [trailer] awning, plug in my amp, and play," says Leggett. "I go to parks, schools, city halls, military bases, public squares, and especially beaches and churches." Leggett, an ordained minister (currently practicing Buddhism), served at Pilgrim United Church in Carlsbad from 1992 until 1995.

For the Peace Bubble tour, Leggett plays solo sets of covers and peace-themed originals; he then videotapes interviews with attendees. He asks them two questions: "Is peace possible?" and "What would a more peaceful world look like?"

"I've recorded around 600 interviews so far," he says of his tape archive, some of which is playable at peacebubble.org. "I'm looking for insight into different worlds than mine." He says many interviews dead-end quickly. "Many people say they don't think peace is possible. I played outside the Rock and Roll Hall of Fame recently [in Cleveland, Ohio], and that's what more than half the people said. That kind of makes the second question pointless."

Leggett took off last year with an $8000 grant from the United Church of Christ, for which he performs at their places of worship along his route. He says he has no other sponsors and is living in the Peace Bubble, subsisting on one meal a day and passing the hat at each stop.
