@ Hamish: Definitely on the morris. We have a couple of sides locally, at least one of which drops by the pub at least once a year.
@ David: We'd expect parents to supervise the kids, but I think a bit of face-painting or something might help to keep them from going nuts.
Aw, Jaysus... I'd forgotten about all that CRB bollox. That really limits what can be done for the kids anyway. No way am I getting dragged into that palaver. The parents will definitely be responsible for the kids at all times.
