That's another of my Whitby memories, missing the last dance and running like ... to fetch child from the creche at lunchtime. And the year they were all taken through the harbour crowds to rehearse for a performance on the beach; on my way across the bridge I noticed a lad talking to a policeman, when I arrived a parent was saying "but where is he?".
I imagine that with the child protection laws it is more complicated to organise events for unaccompanied children now.
