Roger Waters was "miserable" and "snotty" in the 80s.
The 72-year-old rocker has opened up about his attitude problems when he first performed songs from the album 'The Wall' with his band Pink Floyd and insisted he's now a changed man.
He said: "I was poor miserable little f***ed up Roger.
"If I was in this room, I'd be in one of the corners. I'd be dressed in black and I'd have a cigarette hanging out of the corner of my mouth.
"My expression would be one of 'f**k off, leave me alone'."
However, the 'Comfortably Numb' singer claimed he now appreciates his fans much more.
He told The Sun newspaper: "One of the huge changes between then and now is that I used to be a bit snotty with audiences. Now the whole thing has become a sort of love fest.
"I see young people in Buenos Aires or Split who can't speak a word of English but they're mouthing all the words phonetically, not really knowing what they mean."
Waters embarked on a road trip through France and Italy to visit the places where his father and grandfather were killed in the First and Second World Wars for the film 'The Wall'.
He said of the project: "It's very naked, which I like, It unashamedly spreads my past in front of this great spectacle that was the show and says, 'This is what a lot of 'The Wall's about'."
Roger added: "I feel extraordinarily fortunate to have made something considered significant in terms of its content ... and also really popular."
