Against Piracy

I see all these questions here being answered with 'you cannot perform Mamma Mia w/o a license' yet, I saw advertisements and videos about a production of MM in Tijuana that is obvious it did not have a license and get no answer...It is sad that people can get away with this. Trashing other people's work and illegally

Hello, I came across an add about Mamma Mia The Musical in Tijuana. It seemed weird being that the iconic logo was different.

What is there to do in these cases? The add says they have performaces happening this weekend August 26 and 27.

Here is the info I saw: http://boletea.com.mx/eventperformances.asp?evt=1004
