Despite the fact that I dislike his politics, I do think Lydon is more intelligent than that.
He then formed PiL and wrote some interesting-sounding lyrics, though I have to admit that I do not fully understand what they mean.
In 1990 they did the ecologically-themed "Don't Ask Me" which seemed to be a high point in his political stance. He seems to have gone downhill a lot in that respect in the past 5 years. Then again, perhaps 1989/90 was a high point in the political stance of much of the world... (Berlin wall falling, Nelson Mandela released, concern about ecological issues, rejection of Thatcherism, etc...)
Morrissey is another odd mix of left and right when it comes to politics. Anti-Thatcher, anti-Trump, pro-animal-rights... but stridently pro-Brexit, may have an affinity with English nationalism, and has been accused of racism by some.
Yes, that's the one. Definitely not LeAnn Rimes, who I also remember.
