VIDEO : Neil Young Rocks Out Against GMOs With Willie Nelson's Sons

Rock legend Neil Young continues his anti-GMO campaign against agriculture behemoth Monsanto and coffee giant Starbucks in the song and video for "A Rock Star Bucks a Coffee Shop." For years, the 69-year-old songwriter has shown his support to farmers and disgust for genetically modified organisms as the co-founder of benefit concert Farmer Aid. This latest musical push involves rock band Promise of the Real, fronted by Willie Nelson's sons Lukas and Micah. The rockers helped Young on the track as well as his entire upcoming eco-friendly album, The Monsanto Years drops June 29 on ITunes and other Digital retailers.??
