I grew up concert wise during the punk era where there certainly were a few left wing groups like the Clash etc but also a few that were counter counter culture and hated the left wing politics of the hippies before them. I’ll never forget a small punk show set up by an anti nuke group and had a bunch of local punk bands performing. Well one group called The Forgotten Rebels got on stage and started ranting about how they loved nuclear energy and more than likely the show was being powered by a rather large nuke plant just outside of town. After the show the organizers said they should have vetted the bands better. They just assumed everyone agreed with them. It was a great laugh for me as a yute. :)
Johnny Rotten is pretty much a conservative now.
