It's a Rolling Stones fan's dream come true - the chance to travel with the band, hear their stories, watch them rehearse... and it happened to celebrated rock photographer Denis O'Regan after he was invited to be the official snapper of their tour in 1982.

"The biggest surprise was the lack of decadence," he recalled. "This was 1982, they were slightly on the way down from all of that. The plane was laid out like an apartment, and all the rock gods you'd expect to see doing something mad were more likely to be eating sushi, watching a film, or reading. There was lots of reading."
