Queer Arts Show Launch
If it's important for you to find ethical cabaret with a noble mission (and in these kooky times it probably should be) then you could do far worse than the opening show of the Southwark Queer Arts Week. It's the brainchild of Open Doors London, who provide support and services to older LGBTQ people, and Loud and Queerly, a cabaret collective focused on equality and human rights. So yeah, very much a show by and for the people, with a ready roster of performers who've donated their talents so you can watch 'em for free. But you could always do the nice thing and donate some dosh too.
