Grendon Underwood’s popular two-day festival has been cancelled, just days before it was due to get underway.
Flooding at Grendon Broadway has forced organisers to postpone the event, which was due to start on Friday.
This year’s highlight were tribute acts to Oasis, Kings Of Leon and The Killers.
Festival spokesman David Evans said: “After a site visit today it has become clear that we cannot run the festival as planned this weekend.
“We cannot get the heavy lorries into the waterlogged field in order to build the stages and we certainly cannot lay the necessary electrical cabling.
“This is a massive disappointment for many, many people who have worked heart and soul for the last seven months to build this event. Not to mention the bands, the suppliers and the huge number of ticket buyers. We just have to be safe.
“We are currently looking at alternative dates and are contacting all parties. We will update everyone as soon as we can.
“Tickets will of course be valid for the new dates.”
The festival, which takes place every other year, started out eight years ago with 300 people.
In 2010 it attracted 2,000 and this year organisers expected 4,000 through the doors.
Last year the not-for-profit event raised £11,000 for the Aylesbury-based Florence Nightingale Hospice.
It is organised by a team of 10 core volunteers.
The Bucks Herald understands that organisers are looking into the possibility of staging the festival in September.
Mr Evans said: “We are trying to contact all the bands and suppliers, but to get exactly the same line up on a future date would be difficult.
“We are absolutely despondent after months of intense hard work putting everything together.
“It is not just the committee, it is all the other people that have promised to do things. The community has pulled together and huge numbers of people have given up their time.
“We have contacted every ticket purchaser by email, we have updated the website and Facebook and been doing things on Twitter.
“We want people to understand this was the last resort.
“We are desperate not to waste all the effort work and effort which has been put into this. But we have to be safety conscious.
“The fact is we have to lay electrical cables to supply the power for every area of the site from the bands, food, drink and stalls.
“And with all the standing water it would not have been safe.”
