PBS (Sat., Mar. 8, 9:30 p.m. ET)
I used to love listening to PP&M singing Where Have All the Flowers Gone, Blowin’ in the Wind, If I Had a Hammer and even Puff the Magic Dragon. I still do. Their jokes and sweet-’60s observations on life (“Love’s a pretty powerful thing”) may date Peter, Paul & Mary now. But their songs don’t get old. Like their concert audience in Nashville, I’m giving them standing ovations.
