Hi ,when I first heard this song I didn't realize it was categorized as a protest song until later in life , when songs seemed to be 'categorized'. It is by Five Man Electrical Band and is called :Signs

The good thing about categorized music is that I can go straight to the 70's section if I go to the shop.
I will post 2 more favourites from that era:

Women In Uniform The song was written by the band's bass player, Greg Macainsh. Shirl's voice is perfectly suited. (imo of course)

Midnight Rambler Written by the Rolling Stones. I particularly like the last 2 lines as it is an unusual way to end a song. "I'll stick my knife right down your throat baby. And it hurts."
