In the spring of 1941, Woody Guthrie travelled across Washington and Oregon, composing 26 songs that extolled the virtues of Grand Coulee Dam and the electricity it produced. The songs included favorites like "Roll on Columbia," 'Pastures of Plenty," and "The Biggest Thing that Man has Ever Done." Collectively they are known as "The Columbia River Songs."

"He plucked tunes about the people, the mighty Columbia River, the beautiful Northwest landscape and the promise of prosperity from new hydroelectric dams," said Libby Burke, an archivist for the Bonneville Power Administration, the Portland-based federal agency that hired Guthrie.

Obviously, Thames Tideway should sponsor a folk singer too!
