I was watching a PBS special the other night, featuring Peter, Paul and Mary. I was fine 'til they sang "We Shall Overcome," followed by Mary singing "For Baby, For Bobby" as she held her granddaughter in her lap, each looking adoringly at the other. The frosting on the cookies was when Ritchie Havens joined Peter Yarrow on "The Great Mandala." I was reduced to a puddle. Blubbering, that is.
