Richie and Capaldi’s performance marks their debut at the UK festival, while Duran Duran’s appearance is billed as a UK festival exclusive.
On playing, Lionel said: “I’m excited to be playing at The Isle of Wight Festival next summer. It’s the first time I’ve performed at the festival and I can’t think of a better way to start the summer! It’s a festival steeped in music history – Jimi Hendrix, Bob Dylan, The Rolling Stones have all headlined and I’m honoured to be joining the esteemed list! See you all there.”
