Mary Travers has passed away.

Mary Travers, one-third of the hugely popular 1960's folk trio Peter, Paul and Mary has died.
Travers, 72, had battled leukemia for several years.
Travers joined forces with Peter Yarrow and Noel Paul Stookey in the early 1960's.
The trio mingled their music with liberal politics, onstage and off. Their version of "If I had a Hammer" became an anthem for racial equality.
They were vehement in their opposition to the Vietnam War, managing to stay true to their liberal beliefs while creating music that resonated in the mainstream.
They disbanded in 1971, launching solo careers-Travers released five albums-that never achieved the heights of their collaborations.
This marks the end of an era. Peter, Paul and Mary were certainly part of my teenage years and to find that Mary Travers has passed away is sad and that does not adequately express my thoughts on this event.
