RED ROCKS AMPHITHEATRE — The stars are all here, with Sheryl Crow, Sugarland, Dave Matthews and political heavyweights.

Crow hit the stage ready to rock, getting a huge response for her song "A Change Could Do You Good" — the perfect theme for a political movement based on change.

"It’s been a long time since we’ve had a leader that inspires the best in us," Crow said, telling the crowd to ignore the negative ads portraying the change movement as naive. "It's important that the highest office in the land be held by someone who inspires greatness in us and inspires hope. Hope is important, and it's what this country is based on."

The "green" concert was started with an idea from Mayor John Hickenlooper and environmental activist Laurie David. Both of whom spoke onstage. Crow immediately signed on; David approached Sugarland, the members of which have been longtime green supporters. Hickenlooper himself approached Matthews, as the two have a relationship after the Katrina benefits at Red Rocks in 2005. Also on hand: Gov. Tim Kaine of Virginia, Sen. Ken Salazar and Robert F. Kennedy Jr.
