Not sure about that, tho, Joe. Think of the implications behind songbooks like Ewan's Shuttle·&·Cage & Lloyd's Coaldust·Ballads. Excellent, indispensable books that singers of my generation could hardly do without; but with a clear tendentiousness of selection & approach notwithstanding. Published, at that, by the explicitly & self-avowedly Marxist Workers' Music Association.
