Please help me with program wording....? - ceremony program thank you wording

Well .... is small backyard ceremony on Sunday at noon. Pre-Play's ceremony when the guests arrive, and a juice and coffee and Danish pastries Buffet little space on deck.

So, according to plan when it is time to begin the ceremony, my brother playing opportunities and ask everyone to sit down. (Later, another song for the mothers of entry and another song for the wedding, etc.)

I try to write the program for the ceremony and the list of songs played. This procession and the recession, but

What do you call if the guests invited to spend?

and what will be called when the mother is accompanied on seats?

I really need to use ideas for words.
Thanks
