Songs of Conscience an 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.
