I'm not a member of the tour, I don't really know anything about how it is conducted. I was surprised to hear you say that the tour isn't mentioned on the DPJ site, so I went to have a look. You're right. It's not there anymore. So maybe it's over. I don't know.
I saw the show live when it was in San Francisco, and I've seen Poetri on the HBO show. At the live show, there were a lot of great performances (it's poetry, but there is a LOT of theatre going on), and a couple weak performances. The one young woman with the poem about her mother in the kitchen, cooking traditional Spanish (I think?) meals, man, that was amazing.
Anyway, contact the performers. Send a PM to Poetri, or try someone else you've seen on the show. Most of them have Web sites. Ask them. In fact, ask two of them. See if they both respond with the same info, or completely different stuff.
