Songs of Conscience and Concern: A Retrospective Collection is a 1999 compilation album by American 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 1980s and 1990s material, it's a profile of the group's most serious songs from their second phase.[2] 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.[3]
