After Eric Burdon tore through "Water," a song from his new album 'Til Your River Runs Dry, last night on Late Night With Jimmy Fallon, the rock & roll veteran stuck around for a classic, performing a web-only version of "We Gotta Get Out of This Place." The Roots laid down a slinky groove on the 1965 single Burdon recorded with the Animals, and the singer growled out the lyrics as the tune built into the cathartic chorus that made it an enduring sing-along anthem.
