Pete Seeger may be 91 years old, but the iconic folk singer still has plenty to protest. On Friday night at New York's City Winery, Seeger debuted a new song he wrote about the disastrous BP oil spill as part of a fundraising concert for the Gulf Restoration Network and Global Green USA . "It's a strange, strange song," said Seeger about the new tune, which featured a simple finger-picked chord progression and gravelly ominous lyrics like, "When the drill baby drill turns to spill baby spill/God's counting on me/God's counting on you."
