DEMOSTRATION?¡?¿!

Hello everybody!
I've a question. I'm not sure but I think that Adria said something about a manifestation. He was doing refernece for a demostration against the one that happened in Madrid (civil rights, gays, etc.)
Please Adrian tell me something. Said to me WHEN and WHERE. I'm waiting for your answer!!
Thanks a lot.
Someday i'll write morethings. BYE!
