What ever you do don't play hide and seek if you have an old chest hidden around anywhere. Don't take my word for it -- see "The Mistletoe Bough".

We have a set of large cards with pictures of the articles for "The Twelve Days of Christmas". When we perform at Christmas functions we hand them out to groups of people. Then I run around and point to each group as their turn comes and they sing (and sometimes also act) their bit. We all sing the partrige in the pear tree line.
Cheers, Joy
