I live in Southern CA but will travel and sing most anywhere.  I am a professional Hawaiian Wedding Singer.  I am the first to arrive, and play tasteful ukulele music as guest and family are seated and awaiting the processional.  I sing a different song for each in the processional, and when the bride is ready to walk down the aisle, I blow the pu (shell) to announce her.  

Most requested song for her march is the Hawaiian Wedding Song, or Iz's 'Somewhere Over the Rainbow' .
