After Tom Paxton invited him to come to New York City in 1964,  Eric Andersen became a vital part of the Greenwich Village folk revival. More than 50 years later, at a youthful 75, Andersen is living in Amsterdam with his Dutch wife, Inge Andersen, and is as active as ever. He's recently released two albums in Europe, one dedicated to the work of Albert Camus and the other to Lord Byron, and Legacy Records is issuing a two-CD, 33-track career anthology, The Essential Eric Andersen.
