Sir Elton John set a record at this year’s Glastonbury, becoming the most-watched headliner in the festival’s history, with more than 7 million people tuning in live to the BBC to watch his last ever UK performance.
The 76-year-old singer certainly delivered all his characteristic showmanship. But many who have followed his music over the decades will have noticed how much his voice has changed during his career – and not only because of the surgery he had in the 1980s to remove polyps from his vocal cords.
Equally, it’s not all down to the process of ageing. While it’s no mystery that this affects every part of our body, it isn’t the only reason that a person’s voice – even a professional singer like Sir Elton – can sound quite different over the years.
