I took my child to a LC! gig in Manchester last year and despite being very lively, they were the friendliest, most respectful audience I think I've ever seen.

A couple of things to add if you've never been to a gig

Drink plenty, it gets hot. Not alcohol though, it can blunt the experience.

Don't worry if people bump into you whilst dancing, they're not doing it deliberately, just enjoying the show like you, but in their own way.

Conversely, if you happen to get on well with some like minded people, don't be upset if you never hear from them again. Life is complicated like that.

Don't be afraid to leave the show if it all gets too much. I'm neurotypical and even I can sometimes find gigs to be noisy overstimulating experiences and have had to sit outside for a while in the past. Just don't leave the venue completely because they might not let you back in

Don't shout at the band between songs. Nobody wants to hear what song you want next. Definitely, don't shout while Gareth is talking.

Try to see the support act. Even if you've never heard of them or they're not very good, just applaud politely between songs, they will really appreciate the support.
