This album has had over three decades to make an impact, and it says something for its staying power that, in the face of more recent, more generously programmed, and better mastered compilations of the duo's work, it remains one of the most popular parts of the Simon & Garfunkel catalog – which doesn't mean it isn't fraught with frustrations for anyone buying it. Its very existence is something of a fluke – in the spring of 1972, the five original Simon & Garfunkel albums, Wednesday Morning, 3 AM, Sounds of Silence, Parsley, Sage, Rosemary & Thyme, Bookends and Bridge Over Troubled Water, were still selling almost as well as they had in the 1960s; indeed, Bridge Over Troubled Water had carved out a seemingly permanent place for itself on the charts for years; and between the continued radio play of the duo's biggest hits, and the inevitable discovery of their catalog by successive new waves of junior high and high school students, those five LPs stood among the most profitable parts of the Columbia Records back catalog, rivaling Bob Dylan's much larger library in sheer numbers.
