If so do you have any advice for DS who would like to try it at Christmas? He doesn't sing but plays guitar. He's very good and he'd like to earn some money for a charity that's important to him. We live in a safe city but it does have a set of regular loud messy drunks who hover in the centre and I'm worried about him getting robbed, so I will sit very close. He doesn't need a license and I haven't seen any age restrictions on the council website. Anything else we should know?
