Andy Williams set to play Glastonbury

(GETTY)

Andy Williams has announced plans to perform at Glastonbury – aged 82. The American crooner said Michael Eavis has invited him to perform at the festival's 40th anniversary next year.

An audience at the Cheltenham Literature Festival cheered when Williams, pictured, now 81, said he had been booked. John Wilson, a host on BBC Radio 4's Front Row, said: "I had asked him if he had any plans to play any more gigs and he said he had been asked to play at the festival."

Next year's event sold out in less than 24 hours earlier this month, and it has been rumoured that the Rolling Stones will appear. This year's festival attracted 137,000 music fans and featured acts such as Blur, Neil Young and Bruce Springsteen.
