Neil Young has always loved a good cause. His latest is joining forces with Farm Aid co-founder Willie Nelson to play a benefit concert for an anti-pipeline group in Nebraska next month.

Bold Nebraska says the two legends will play a show called 'Harvest the Hope' on a farm near Neligh, Nebraska (about 80 miles southwest of Yankton, South Dakota) which is in the path of TransCanada's proposed Keystone XL pipeline. The company has already built a southern leg of the pipeline between Oklahoma and Texas. Critics of the project fear it could contaminate groundwater and contribute to pollution in Nebraska.

The daytime, outdoor concert will be in a field on a farm owned by the Tanderup family, part of a collective of Nebraska landowners refusing to sign an easement with TransCanada for the pipeline that would carry oil from the tar sands of Canada to refineries on the Gulf Coast.

Tickets are $50 and go on sale today (Wednesday August 20) at 10am central at this link.
