Festival goers flocked to see the 68-year-old in their droves and she gave an impressive hour long set, with all her biggest hits, including Jolene, Nine to Five and Islands in the Stream.
Dolly looked her usual glam and gorgeous self, clad in a skin tight, rhinestoned white jumpsuit, bright red lipstick and matching nails and heavily coifed, big blonde Texas style hair.
The crowd, who had spent the vast majority of the weekend dealing with torrential rain as they traversed the mud filled fields of Glastonbury, clearly enjoyed every minute of Dolly’s performance, cheering wildly and singing along throughout.
Errr... HELLO EVERYONE... a Benny Hill saxophone homage no less!!!!!
But, those sitting in the dry, warm comfort of their homes—watching the performance live on the BBC appeared to have a different view.
Sky News presenter Kay Burley was among many who tweeted their disappointment—accusing Dolly of not singing live.
"Oh, Dolly is miming. How disappointing,” she wrote.
But, comedian Stephen Fry leaped to Parton’s defense.
"That's not miming. If it appears not always to lip-sync that’s an HD live processor issue. You see it with reporters," he tweeted.
And, Dolly’s rep quickly jumped into the fray.
"No, she sings live,” they insisted. "Some people don't know an amazing singer when they hear one."
Amen to that.
