Simple Minds rocker Jim Kerr always performs in white because it reflects the band's purity and spirituality.

The Scottish singer confesses he has 100 white shirts he rotates for gigs and it has become more than a habit to dress in white.

He explains, "That man in black thing - so loved by countless rock stars - just doesn't suit. It's just not what I am about.

"For me it has to be white. Maybe it is because I feel that white is the colour of peace and purity, the colour of spirituality itself. The simplest of colours.

"Perhaps that is why I associate wearing a white shirt with performing with Simple Minds."
