I got married at the Catholic church in San Jose on 10/28/06. It IS true that our church in the US had to send Padre Juve Gonzalez (the priest) a letter saying we working on our marriage requirements before we could book the church. You CAN bring in outside music, but I think you need approval from Padre Juve. We used a group that he recommended (vocalist, harp, guitar, etc.) and our music was great. You can PM me if you have more questions. Good luck.
