Tips for the next Cantata/Concert

Don't make the theme "Africa".
Don't make 12 year-olds sing "Oh Happy Day" when you know there just gonna sing "Oh Crappy Day" instead.
Don't bring your brothers iPod and he doesn't know. It's liable to break.
Also, don't bring a giant slab of chocolate and leave it in your bag, which also contains your brothers broken iPod, your new phone and headphones. Never leave it on the seats, where someone's gonna sit on ya bag and the chocolate will explode over all your possesions.
Turn down the heating.
Don't put on "My Big Fat Greek Wedding".
Don't do it on someones birthday either.
