The idea that Johnny only says negative things about M is a long-running gripe... a really entrenched, long-running thing. He was complaining about it 20 years ago ("he says Morrissey is evil and The Smiths was a terrible experience" - 2002) and in Autobio, he seems to have an absurd dossier of every negative headline and article since day dot. It's sad because in obsessing about some offhand comments in 1995 or whatever, he's missed a lot of very kind and sincere things that Johnny said in recent years and that the media haven't bothered to report because it's not as entertaining. I think some people around Moz feed that perception / narrative for their own ends, sadly. It suits them for Morrissey and Marr to be estranged.
And people like Jesse and Nile don't help either . Especially Jesse. He's annoying about jm.
