Ah! Happy days, being woken at 3am by SGs to say "Mr OnCallEngineer, there's a red light showing in building xyz". Then driving 25 miles in the pouring rain into Wales to find a neon that had been happliy glowing for years but only just noticed! Neeearrgghhh! Here!! I just thought, you don't suppose they saved it up for the foulest night possible just for a laugh do you?
