Singer will play before Jay-Z on the main stage
The star will play a slot on the Pyramid Stage on June 28, directly before Jay-Z‘s headline slot.
Festival organiser Emily Eavis told BBC Newsbeat that she was confident that Winehouse could be relied on. “I have total faith,” she said. “I think she’ll come and deliver.
“This is one of the biggest sets of the summer, supporting the most anticipated artist at Glastonbury in the past 38 years.”
“I don’t know how much [speculation that she is unreliable] is hot air from the press and how much is reality but she is pretty reliable actually. It’s her personal life and no-one really knows the extent of what she’s up to and I don’t think it should be public knowledge.
“We all know she’s a brilliant performer and I think that’s what we should be focussing on.”
