I know its not primary school, but my eldest has just left secondary and they had a leavers do at mitton fold and he went in his tuxedo in a green camper van
They also had a leavers mass (catholic school) and at the end of it they had loads of photos on the big screen of their time through secondary school... He's just got the DVD of the mass and leavers ball and we had a good laugh at all the pics, its amazing how much they have grown up since year 7 to now
Oh yeah and he went on a 5 day trip to barcelona after his exams had finished and he had officially left school
