Potentially controversial opinion but I don't think old songs should be cleaned up and censored of the worst of their lyrics if the songs are still being played and performed. Like give the whole thing or don't play it, you might not like having to go "yes, it was a different time" when the Oh Fucking Yikes lines come in, but if you don't do that, there's going to be people who weren't there and will confidently go "actually things were never like that at all", because the sources they were being exposed to decided to skip the parts that were nasty.
Like if a song about being a working class youth living an awful life in an awful place requires me to look up up what the fuck a blue shirt is to understand "my daddy was a blue shirt, my mother a madam", I'm going to question why we suddenly decided to chicken out on elaborating what the brother was doing while earning medals in Vietnam.
