Hi, I've been asked to DJ at a mate's wedding (something I've done loads of times before), but the venue are kicking off about it saying that i need public liability insurance. if i'm hiring equipment from somewhere, do I need this, or shoudl it come with the equpment? And if I do need it, does anyone know anywhere where I can get it for a one-off event relatively cheaply? any help much appreciated. Thanks, R.
