My version of THE RED FLAG was sung on the World March of Women in Brussels 14th October (New York World March presenting petition to UN on 17th October). My version is called THE PURPLE FLAG:

THE PURPLE FLAG

The purple flag we recollect
Was carried by the suffragette.
Unfurled it was in Downing Street
Above the ranks of marching feet.
They raised the purple standard high.
"Votes for Women" they did cry.
For many a year they struggled on
Until the women's vote was won.

For sixty years the men did say:
"We shall not grant you equal pay.
To be a wife and mother fair,
There is no job that can compare."
We raised the purple standard high.
We went on strike. We questioned why;
And then the cause was won at last:
The Equal Pay Act it was passed.

But still there's many obstacles
For people without testicles.
Through a glass ceiling we can see
The men who rule society.
So raise the purple standard high.
Within its shade we'll live or die.
We'll not give up our valiant fight
Until we've gained true equal rights.

PS: Tony Benn isn't the only Labour Party person who knows all the words of the original. The Labour Party members in Strawberry Thieves Socialist Choir also do!
