To mark the 40th anniversary of Australia's first forest blockade at Terania Creek in 1979 Earth Matters presents a program in which musicians Brenda Liddiard and Lisa Yeates reflect on the songs that came out of that event as well as from later protests at Grier's Scrub and Mount Nardi. The role of music in securing victories, unifying blockaders and spreading the word, and the way in which the songs lived on through further protests, is also discussed. The songs heard during the program are drawn from the Lock On CD, which was compiled by Andy Parks, and a documentary about the Nightcap campaign which was produced by John Seed in 1982.Guests: Brenda Liddiard (www.brendaliddiard.co.nz) and Lisa Yeates.Some of the music heard in the program, and much more besides, can be listened to and purchased via the 'Lock On! Songs To Save Australia's Forests' compilation bandcamp page. All proceeds go to North East Forest Alliance- https://nefa.bandcamp.com/releasesEarth Matters #1205 was produced by Iain McIntyre
