Saying I know him would be stretching it.
I spent a drunken weekend in Ireland and Northern Ireland several years ago and ended up hanging out with him and a bunch of random other people I didn't know. Very long story - and literally me being crazy and a bit strange rather than any back story or employment opportunity.
Really nice bloke. Really interesting. But undeniably screwed up by what I thought was too much touring and never being settled in one place. I've met people before like that who are almost too worldly to the point that that struggle to connect with normal life and people living a normal life. I only found out about his father after, but it does fit together.
He is one of those people I could genuinely listen to chatting for hour and hours on end. But I also found him clearly lonely in a way that's difficult to describe and very sad.
From what I've read, I think he has generally sorted himself out a lot out since then - I think he was pretty rock bottom at that point from what he's said in interviews.
I hope he eventually finds whatever inner peace he's been after.
