HELP! -Ceremony songs with Mariachi Band? in Wedding Music & Entertainment Posted June 2, 2010 We had a mariachi band at our wedding. They played for two hours before the ceremony and after the ceremony. They also played our exit song, which was Marcha Nupcial. This is what I did: I went to Amazon.com and under MP3 downloads and did a search for mariachi wedding music. You can listen to a few songs on there. If you need help, I can provide you with my wedding song list that I put together for the the Mariachis.
