Valentine's day disco plan

Year 13 and year 12 have planned to have a valentine's day disco on the 14th of February. We have planned to use the school's speakers and our own dj set. Year 13 would be responsible for the music and sandwiches and year 12 would be responsible for the decorations and other things. Our aim is to entertain the students and add some variety to their lives, as for some students their life exists at home, at school and in the car that takes them to school...for ourselves we would like to gain experience of organising music at an event as we have never done it before.
