The Pretenders are back. They are, without doubt, one of the best groups in the history of rock. And they're back. It seemed as though their charismatic leader, Chrissie Hynde, had called time on the band when in 2014, at the age of 62, she released her first solo record; what's more at that point, they hadn't played live together for five years. But no - The Pretenders are back.
