High Quality Content by WIKIPEDIA articles! Songs of Conscience and Concern: A Retrospective Collection is a 1999 compilation album by folk group Peter, Paul and Mary. It was the group`s second compilation, following 1970`s Ten Years Together: The Best of Peter, Paul Mary. Drawn primarily from the trio`s `80s and `90s material, it`s a profile of the group`s most serious songs from their second phase. The sole new song, "Don`t Laugh At Me", has since become a classic in its own right, evidenced by its inclusion on their most recent greatest hits album from Rhino Records.
