I think it would have been cool if I was there playing or singing. I don't doubt it must have been very fun and since they seem to be my "paisanos" (I live in Monterrey aswell) I won't criticize the musical quality, hehe :). It's just a bunch of guys having fun with Queen karaoke and a drummer. I hope they would invite me next time, haha :D.

Yup, that'd be Monterrey, Nuevo Leon, Mexico. The third largest city in Mexico. The first two being Mexico City (largest city in the world) and Guadalajara.
Still, I don't understand why you posted that, haha :). Are you by any chance the drummer seen in the videos? That'd explain things.
