Dotted around the auditorium are plaques commemorating the association's heyday of offering "friendship and happiness to elderly people", newspaper clippings of afternoon tea visits and invitations from Ladies Cobham and Fergusson, wives of Governor Generals.
But although its past is fascinating, the hall's current happenings are even more peculiar and exciting. Still owned by the Old Folks Association, and in spite of the rudimentary set-up, the hall has become an independent, affordable space for some of the most cutting-edge, experimental performances in the city.
The roster of hall appearances is a fringe/avant-garde Who's Who (if that's not an oxymoron): Alexa Wilson, Sean Curham, Cat Ruka, Vitamin-S, Phil Dadson, Fiona Jack and Peter Robinson.
I've seen actress Nisha Madhan making "snow" angels in flour for playwright Louise Tu'u, in Gaga: The Unmentionable (on the frustrations of language and immigrant experience); and I was amused (and relieved) when actor/comedian Johnny Brough - as an audience member - seriously wrestled theatre maker Stephen Bain to stop him from literally pouring money down a drain in finance-critiquing Free Happiness.
The aim, says Curham - who acts as hall custodian, aided by a brains trust including artists Alex Monteith and Mark Harvey - is to support non-commercial "performance research": "programming that's not viable anywhere else" and that therefore wouldn't otherwise happen.
As an occasional hall spectator, I am intrigued; as someone who cares about the diversity and depth of Auckland's performance culture - particularly about works critiquing or commenting on power - I am overwhelmingly grateful (although I wish there was more than a hit-and-miss way of finding out what's on).
Perhaps there's a connection in spirit as well as history to Baker - dancer, civil rights activist, integrator of theatres, winner of the Legion d'honneur and adoptive mother of 12.
