We celebrate the new year by saying farewell to the disastrous 2020. We play some comfort music and protest music by freethinking songwriters, performed (mostly) by freethinking singers. We hear Irving Berlin, George and Ira Gershwin, Yip Harburg, Jerome Kern, Stephen Sondheim, and more — performed by Tom Lehrer, Linda Ronstadt, Joni Mitchell, Pete Seeger, Nina Simone, Elton John, James Taylor, Cher, Dan Barker and Shelley Segal.
