Being a pop star used to mean having a nice face and a good voice, and learning a few dance routines. That no longer cuts it at the top, as Taylor Swift reminded us last week, when she revealed how she had prepared for her Eras tour. “Every day I would run on the treadmill, singing the entire set list out loud,” she told Time magazine. “Fast for fast songs, and a jog or a fast walk for slow songs. Then I had three months of dance training, because I wanted to get it in my bones.”
If you have seen Eras live, or watched it at the cinema, you will know why she had to put in the work. Part pop extravaganza, part endurance feat, it involves almost three hours of costume changes, vigorous dancing and sprints from one end of the stage to the other – all while belting out songs. As the colour rises in Swift’s face and the sweat gathers at her hairline, you start to feel tired yourself. Swift is not unique. Beyoncé’s film Renaissance also documents the physical labour required for a tour, while 65-year-old Madonna’s current Celebration tour, which is due to conclude next April after 78 shows, makes clear how long that commitment can last.
