“Just because I’m famous doesn’t mean that I work for the audience,” says Canadian singer/songwriter Neil Young. “I’m not obligated to do anything. I’m an artist. I will do what I want to do. Whatever the consequences ... I certainly hope that it’s a civilised reaction.”

What is the 62-year-old “Hurricane” rocker talking about?

Young has unveiled his brand new documentary: CSNY: Deju Vu, which he’s directed under his nom de plume, Bernard Shakey.

The film captures the tumult which followed Young on 2006’s “Freedom Of Speech” tour, when he took to the stage with former bandmates David Crosby, Stephen Stills and Graham Nash.

Faced with hostile crowds who were unhappy with the singers’ anti-Iraq stance (Young was recently hit with death threats), the movie – which opens in US cinemas this week – is a fascinating look into America’s political heart.

“I hope that when they leave that they talk about it for a while, and that when they wake up the next day they still have some images from it in their mind,” Young admits of his audience. “The rest is up to them.”
