Tony Christie described playing Glastonbury as 'a great honour'
Tony Christie, famous for his hit (Is This The Way To) Amarillo, is to appear at this year's Glastonbury Festival.
Christie, who said he was "in awe" of the event, will play on the main Pyramid Stage on Sunday afternoon.
He follows classic stars like Neil Diamond, Dame Shirley Bassey, Brian Wilson and James Brown, who have all played Sunday slots in recent years.
Veteran acts look set to dominate this year's event, with Neil Young, Blur and Bruce Springsteen topping of the bill.
Franz Ferdinand, Lily Allen and Fleet Foxes are among the other acts already confirmed.
The full line-up will be announced nearer the event, which takes place in Somerset from 27-29 June.
A limited number of tickets will be put back on sale next weekend
Fans can expect to hear Christie perform songs like I Did What I Did For Maria and Avenues and Alleyways, as well as Amarillo, which spent seven weeks at number one in 2005 after it was re-released for Comic Relief.
His last album was produced by Mercury-nominated singer Richard Hawley, and saw him cover songs by fellow Sheffield acts The Arctic Monkeys, Pulp and Human League.
Christie said he was "excited" about playing Glastonbury. "I'm going to do some of the new album tracks and I've got to do my old stuff as well," he told BBC News.
"I did the V Festival three years ago but I think Glastonbury is the big one, so it's a great honour."
More than 132,000 fans will descend on Michael Eavis' dairy farm for Britain's biggest and most famous music festival.
Tickets went on sale last October and sold out by February. A "very limited number" of cancelled tickets will be put back on sale on 5 April.
