After Eddie Vedder declared himself anti-war and quoted John Lennon’s “Imagine” in an open letter last week, he covered the famously anti-war song for the first time during a solo show in Portugal on Friday night. Before the song began, he said, “I think it is the most powerful song ever written. Which is why I have never played it. It seems like maybe there is a reason to play it. If you’d like join me or use your voices or hold a light there might be some people out there that need to know they are not alone.” Watch a fan video of the performance below.
