can anyone name some songs of the 70's that....??

Not really the 70's but Midnight Oil sang a few tunes like what you describe?!

Although it was recorded in America, Helen Reddy's "I Am Woman" saw the beginning of the Women's Liberation movement of the 70s. Other than that, I guess you'd have to look at Skyhooks - particularly their "Livin' In The 70s" album. They had in Greg Macainsh a songwriter who wrote about local topics and issues. It was the first time songs had been written about Carlton and Toorak, and issues relating to sex (and sexuality) and drugs. Other than that, you'd have to look at less "popular" writers and singers like Margaret RoadKnight, Bob Hudson and possibly Richard Clapton.

Try the songs of buffy saint marie, bob dylan , joni mitchell . There where many protest songs about the treatment of the American Indian just transfer they're meaning to the Aborigine's.

get Bee Gees, Olivia Newton John, Sheena Easton, Diana Ross, Stevie Wonder, and lot more. well, those are only artists i can think of basing on what i have in my music library.

No I don't know any songs of your description but i guess if you go on google.com or askjeeves.com you could get some answers.
