Continuity mistake: In the final scene at the party when the conga starts, Julie is at the front followed by Freddie, Jackie, Zammo, Mrs McClusky, Ronnie, Gonch, Louise, an extra, Calley, Robbie wearing an orange and green party hat and Trev. Then when the conga goes through the door and out into the playground the first 5 are the same, followed by Ronnie (who is now wearing a party hat), Gonch, Mrs Reagan, Jane, Hollo, Calley, Robbie (now wearing a yellow party hat), Cheryl and Trev (who is now wearing the hat Robbie was wearing). As the conga goes round the playground Hollo disappears from the line up and Louise moves further back.
