Willie Nelson, Neil Young Plan Cornfield Protest Concert

(AP) - Willie Nelson and Neil Young are planning to hold a protest concert in a Nebraska cornfield.

The September 27 concert near Neligh, Nebraska, is organized by opponents of a proposed pipeline from Canada to the Gulf Coast. The cornfield is in the path of the proposed TransCanada Keystone XL pipeline.

Critics say the plan could contaminate groundwater and contribute to pollution. TransCanada says the pipeline will have upgraded safety measures.
