Tour promoter John Giddings presents the second part of this insider’s guide to the music business, which this week focuses on how live performances have become a billion-pound industry.

John takes us backstage at U2’s last world tour, which made a record-breaking £500m, and talks about the logistics of putting on such a global event.

He also recalls the early years of the Isle of Wight Festival, which he now runs, and the vision of its young promoters.

Phil Collins, Earth Wind & Fire and The Police’s Stewart Copeland are among the contributors sharing their tour stories, and there’s some fabulous archive footage.
