Songs About Time: A Hear and Now Birthday fund drive special, 10 p.m., Thursday, Feb. 13, 2020

KPFA turned 70 last year. Tonight is a different 70th birthday milestone, so host Derk Richardson plays songs about the passing of time. As you listen to Sandy Denny, The Beatles, Guy Clark, David Bowie, Tom Waits, Susan Werner, Bruce Springsteen, the Magnetic Fields, Iris DeMent, and of course Simon and Garfunkel, among others, reflect on the years gone by and prospects for the future, and consider pledging $70 (or half that, $35, or twice that, $140) to keep listener-supported KPFA strong as we forge ahead into “our” next decade.
