WASHINGTON, D.C. — They came from California, Montana, Arizona and Texas for the Live Earth show in Washington D.C., and they all wore -- no, not green -- pink, from head to toe. Maybe it's the new color of choice for the environmentally conscious, but this group represented Code Pink, a women-initiated peace and social-justice movement.

Donning tiaras and T-shirts that exclaimed "no war, no warming," they were first in line to get into the concert venue, having camped out since 11 p.m. Friday night.

"We've been against the war from the beginning and we've been for the planet always... we think there's a real connection between the two. So our message is no war, no warming, go Gore," said Medea Benjamin, co-founder of Code Pink.

The ladies in pink have worked with former U.S. Vice President and Live Earth organizer Al Gore in the past. They were among the thousands who attended the morning show at the National Museum of the American Indian.

"We think that it's great that somebody like him has stood up and said that if we want to continue to live on this planet, we better do something to take care of it," Benjamin said.

Gore sported a green shirt on Saturday, although it was a muted olive green -- much less eye-catching than Benjamin's bright pink.

The D.C. show was a last minute add-on to the eight-city Live Earth lineup. The main U.S. concert was initially supposed to be held in D.C., but plans to stage it there were thwarted by Republican politicians on Capitol Hill.

Saturday's concert in the U.S. capital was a more low-key affair compared to the shows in New Jersey, the U.K., Australia and elsewhere. It was held as part of the all-day Mother Earth concert at the museum featuring native performers.

"Some who don't understand what is now at stake tried to stop this event (from happening) on the (National) Mall, but here we are," Gore told the crowd of more than 7,000, just blocks from the Capitol Building. "It wasn't the cavalry that came to our rescue, it was the American Indians!"

Lack of space on the museum grounds forced many to spill over onto Independence Avenue, where large screens projected the show to concertgoers.

Performing by special request from Al Gore, husband-and-wife country musicians Garth Brooks and Trisha Yearwood played a set list that included only one song: "We Shall be Free." It was their first appearance on stage together since 2005.

Imploring people to sign the Live Earth seven-point pledge, Gore said: "Not many years from now, our children and grand children will ask us one of two questions: 'What were they thinking? Didn't they hear the scientist? Didn't they see the evidence? Were they too busy, distracted or greedy, didn't they care? Or they will ask ... how did they get their act together ... and successfully solve the climate crisis?"
