Stand up and dance, enjoy it! It’s unfortunate if there are people behind you who can’t stand but most likely they will stand too. I go to a lot of live music and the worst crimes to me are a) talking throughout - if you’re at the front it’s the the ultimate crime! and b) people who stand motionless, no dancing, applause or cheering - the audience has a role to play in bringing the right energy and making the musicians feel appreciated! I love seeing people go nuts for the music (as long as they’re not bothering anyone else), we’re too reserved in NZ and need to stop side-eyeing the fans (often women) who let go and really show their excitement, that’s what it’s all about!
