It's a long way from Luthuli House to Kelvin Grove, colonial home of the Mother City's ageing gin-blossomed Wasp elite, but it is a journey that any self-respecting cadre worth her salt must make now and then.
Yesterday it was the turn of Evita Bezuidenhout, who was in town to present the Cape Town Press Club with her 2014 Luthuli Housekeeping Report and provide a tub-thumping update of her #CommitYourselfie Twitter "onslaught against corruption and pessimism".
Since its inception last month, thousands of South Africans have taken part, sending selfies to her website with their wishes for the future ahead of President Jacob Zuma's State of the Nation speech tomorrow.
Calling on the country's leaders, she said: "Let them stop and just listen. There is a noise outside in the street. In the roads. In the parks and on the beaches. In the schools and the churches. In the malls and on the mountains. In the cities. In the townships. In the hamlets and in the huts. The people of South Africa are saying, very nicely, 'Enough is enough'. Please, people, don't wait for the guillotine."
As if these noises everywhere were not quite enough, there was also Song For Tomorrow, a Band Aid-ish anthem launched on YouTube yesterday. In addition to Bezuidenhout, it features Karen Zoid, Zolani Mahola, Hemelbesem and the Bergvliet High School Choir belting out such encouraging couplets as "Our roads are grim and full of holes/And we still have to pay e-tolls?" and "The poor are poorer than before/The rich say they're sorry while they're taking more".
Twitter? YouTube? All this emphasis on the future? It seemed too young and trendy for the Kelvin Krowd. I buttonholed Evita afterwards and asked if her otherwise admirable presentation was not lost on her elderly audience.
"Every single person who listens," she replied, "might think and change the way he thinks, and that's already halfway there."
Halfway there? It doesn't look as if this lot will make it to the end of the car park afterwards.
"You know, I don't care!" she snapped. "They must take their Viagra and make it to the end of the car park. Everybody says, 'What about the millions out there?' Well, one life-change can change the world. One life! If Barack Obama as a child wasn't allowed to survive, he would not be there today, and the world we live in would be a different place, né? So, I don't think about that.
"When I start cooking, I don't think of what it's going to taste like. I think of the fun in creating something that other people will enjoy."
With that she was gone. But even as I dash off this report, I can still hear her closing remarks in Kelvin Grove.
"I am sick of the negative. I am tired of the know-alls and well-meaners who never stop whining and moaning. I am sick of intelligent people looking the other way and allowing decay to become the perfume of the day. I am sick of those lazy losers who use racism as a means to an end. I am sick of being a nervous tourist in my own country.
"I am not white, female, Afrikaans, icon or aikona, octogenarian, designer-democrat, right-wing, conservative, or marginalised. I am a South African.
"Ladies and gentlemen, dames en here, meine damen und herren, mesdames et messieurs: Je suis Evita."
And hear her roar.
