Glastonbury-goers have been urged by festival founder Michael Eavis to vote to stay in the EU.
The referendum takes place the day after the gates to the world-famous music event open and Michael has previously encouraged revellers to make sure they registered for a postal vote.
Now, in a new post on the festival website listing five reasons to vote Remain on June 23, he says many fellow farmers would "go bust" as a result of Brexit.

They are accompanied by a picture of Michael with daughter Emily - who organises the festival - holding a placard with the slogan "WE'RE IN".
"We're one of the few really successful economies in the world at the moment - why change a winning streak?" he said in the first of the reasons for backing Remain.
Others suggested "all the most comforting human rights and working conditions of the last 20 years have been introduced by the European politicians" and "all the best car manufacturers around the world have invested huge sums" in the UK because it was in the single market.
Agriculture, which remains the family business, "is better protected by the EU because there are millions of farmers throughout Europe who they care about", he wrote.
"I dread to think of a free market with our food needs. I think that a large proportion of our farmers would go bust."
He also suggested better European co-operation could have avoided the 2003 Iraq War happening at all.
"The Iraq war is the worst foreign policy decision of the last 50 years. Where was that decision made? In our very own parliament.
"If only we had consulted with our friendly European neighbours, who were dead against the war. Just think of all the horror that followed - and is continuing to this day."
The gates to the site in Somerset are due to open the day before the June 23 vote, with music beginning on the Friday.
A bid to site a polling station at the festival was ruled out by officials.
