Hello all, I am having my wedding ceremony in a park next month, and we have everything figured out except music. Since there are no power sources in the park, we can't plug anything in to play music. Does anyone have any suggestions for how we could still have some music play as I walk down the aisle? We do have some friends who play instruments, but our wedding is going to be really really small. Our guest list is 40, and only 4 of those people aren't related to us in some way, and I know we can't ask someone to play music for us and then not invite them to the reception. I'm thinking maybe something battery operated? Any ideas?
