The problem at London was with evening events aimed specifi ally at adults and marketed as party type functions. I attended one so I can say they were indeed very much focussed on alcohol and having a good time no matter the cost.Not my scene. And living in central London or not, the background noises which the animals get used to over time ate vety different to loud music, screaming crowds and at different time of day when they would normally be undisturbed.
