50th Wedding Anniversay

My parents 5oth wedding anniversay is quickly approaching and I feel comfortable with the party plans so far. The party will be at a local community center with about 60 guests, dinner, cake, punch and some decorations. Tables will have gold table clothes, pointsettias(?) and several small glass votves. My brother has put together a picture presentation to music and we have made several cd`s of various music. What else? A toast, a poem or have a block of time for some guests to share their favorite memory? I sent a special sheet of paper out with the invitation for guests to "share" a memory for my parents and add to a scrapebook- that will be on display at the party.
