Use your own karaoke machine or rent a professional set up. Provide a variety of current music and old favorites.

Dress up your "stage" with glittery props like foil curtains and a disco ball. This is also a great backdrop for keepsake photos.

If kid's are shy about getting on "stage," start out with duets or sing-a-longs to loosen everyone up. If you have a bolder group, set up a sign-up sheet so you know who is next in line.

Provide activities for the audience and singers waiting their turn, like face painting, hair coloring, or tattoos.

You can offer a "prize" for every singer, like a rock star tattoo, bracelet, or sunglasses.
