Willie Nelson and Neil Young are teaming up for a benefit concert to help fund the fight against the proposed Keystone XL pipeline.

The Harvest the Hope concert will take place on Sept. 27 on a farm near Neligh, Neb., that is on the proposed route of the pipeline, which is also set to cross the historic Ponca Tribe Trail of Tears. Proceeds from the event will go to Bold Nebraska, Indigenous Environmental Network and the Cowboy & Indian Alliance.

"Farmers, ranchers and tribes that have been standing up to TransCanada are rock stars in my eyes," says Bold Nebraska Director Jane Kleeb. "Now we will have the honor to have music legends Neil Young and Willie Nelson stand with us against this risky pipeline that threatens our water and our livelihoods. It is our hope that President Obama in the end stands with us over Big Oil."

The farm is owned by Art and Helen Tanderup, members of the Cowboy & Indian Alliance, who have refused to sell their land to TransCanada to use for the pipeline.

"Our family has worked this land for over 100 years. We will not allow TransCanada to come in here and destroy our land and water for their profit," Art Tanderup says. "The heartland is more than a place, it's our home. We hope Americans from across the country join us to Harvest the Hope and stop the Keystone XL pipeline."

The Nebraska Supreme Court will be hearing arguments next month in the dispute over the pipeline, which will span 1,200 miles and cost roughly $5.4 billion.
