Bands playing at Glastonbury Festival this weekend are set to pay tribute to the King of Pop - Michael Jackson - who has died at the age of 50.
Festival organiser Emily Eavis, writing on the social networking site Twitter, called Jackson a "truly great artist".
She added: "There will be tributes all over the site all weekend".
Dave McCabe, singer with The Zutons, told the BBC some cover versions are inevitable: "Hopefully, 'cos he's got good songs and it's always a winner."
Many festival-goers learned of the news late last night as DJs scattered around the festival site began playing Jackson's records.
One fan said: "They started playing loads of his music and we thought, 'Oh, that's really strange' and then someone said, 'Michael Jackson's dead' and we were like, 'No way'."
Another reveller added: "Everyone thought it was a joke at first and then people started watching the news and saw it was true."
Artists including Lily Allen, Lady GaGa and Neil Young all play the festival later on Friday.
