Agreed, great set, really enjoyed it - foregoing support to do an extended set ended up working well, thoroughly entertained throughout now they have the discography to back up a longer show.
Laughed when someone requested Neutral Milk Hotel and he tried to start remembering how it went, probably about five people in the room (me included!) would have known it enough to sing along.
Why should it make a difference, women can be perverts too. Also, they are quite often 'enablers' for male perverts.
As far as I know, the Spanish require a license / permit to film things professionally in public. As for the general public, there's a 'freedom of panorama' clause, that covers you if strangers are not your primary subject. But you're right, not really relevant, other than to say this is where we could be heading if we can't stop people behaving like animals.
As for the last paragraph, then ask permission. 🤷♂️ There's plenty of content creators, street photographers etc that do just that, go about it the right way, and ask permission first. There's a lad in New York that goes around asking pretty girls if they'd like their portrait taken, and when they say yes, he produces some incredibly flattering, but decent, photos, pops up on my feed all the time, and never bothers me, because there's absolute consent.
Lets not get silly here, you can admire somebody's looks / beauty without being a total creep about it, a passing glance, a smile or nod of appreciation is a little different, even if it's unsolicited, to focusing your camera on their half naked arse for 20 seconds, and uploading that footage to the internet for 'other like minded individuals,' all entirely without their permission, and sometimes without their knowledge.
