We are on a tight budget so my fiance and I are doing our music for the wedding from music we download to an mp3. We will have our ceremony music (including prelude, Groom's entrance, Bridal Party entrance, and Bride's entrance), plus music during dinner, the first dance song, father/daughter song, mother/son song, and then party music. My question is, how do we keep the music flowing during the day? Do we assign someone to man the music during the ceremony and reception, according to the timing of events? I don't like the idea of asking a guest to do so much work during the wedding but we can't afford to pay somebody to do it. Any suggestions?
