I love the idea of having guests "Sing for their Supper." A friend was married and had a fantastic and engaging emcee. They had a lovely buffet style dinner, but instead of doing a free-for-all or releasing tables by order, the Emcee announced that someone from your table had to "Sing for your Supper." No need for an entire song, but a part of a song and it had to contain the word LOVE. He walked around with a microphone and went to the tables with raised hands. It was great fun- I sang Bon Jovi and many of the older guests even participated. Once your table participated, you were released.
