A sun-drenched Hyde Park welcomes one of the all-time greats, Stevie Wonder, for the close of this year’s BST Festival. The words icon and legend are certainly overused these days, but tonight we are truly in the presence of one. You could add genius to the list too – Wonder was just 13 when he had his first number one. He hasn’t slowed since, going on to release 23 studio albums and win 25 Grammys, along with a host of other accolades.
