In just one week's time hundreds of thousands of party-loving folk will descend on Worthy Farm for Glastonbury Festival 2019.

But while this year's headlines are yet to be written, the national institution has attracted its fair share of eyebrow-raising moments over the years.

From that time poo exploded all over the dance tent to when Jay Z stuck it to Oasis and Adele almost got banned for life, here's a look back at the most outrageous moments ever...

Jay Z laughs in the face of Oasis

No one really knew what to think when hip hop artist Jay-Z was announced as headliner in 2008.

But Oasis' Noel Gallagher's mind was made up, with the rocker sniping, “I’m not having hip hop at Glastonbury. It’s wrong.”

Needless to say, drug dealer turned international music mogul Jay-Z didn't give a hoot and came up with a sassy way to really stick the knife in.

There was a mass intake of breath when he walked out onto the Pyramid Stage with a guitar slung across his shoulder and began to sing Oasis' Wonderwall.

Burn.

The poo explosion

Back in 1998, the dance tent was flooded by six inches of mud so organisers came up with the ingenious idea of sucking it up with a toilet truck.

That proved to be a grave error. Instead of switching the setting to suck, the operators had the machine set to blow and the whole tent was covered in human poo.

It was so gross that the tent had to be closed off for 24 hours while it was thoroughly disinfected.

Robbie Williams goes rogue

They might have been from the same city, but there was no love lost between hard man rockers Oasis and boy band Take That.

And there was no member of the clean-cut group that Liam and Noel Gallagher found more offensive that the 'fat dancer' Robbie Williams.

However, the feud went out of the window at Glastonbury 1995 when Robbie was seen hanging out with Noel.

Leaving the cod piece at home, Robbie did his best impression of a rogue as he swaggered around in a trackie with a blacked-out tooth and a fag in his mouth.

His foray into rock and roll was to cost him greatly with Robbie promptly getting kicked out of Take That when he returned from his soujourn.

Adele burps at fan and swears more than she sings

She was warned. But despite stern words from the BBC about her notorious effing and jeffing, Adele just couldn't help herself when it came to her 2016 performance.

Far from keeping it clean, she brought down the Pyramid Stage by swearing a whopping 33 times throughout her 90 minute headline set .

She couldn't even get through her first song - Hello - without stopping to tell the crowd "You are f**king amazing!"

Social media erupted with a torrent of righteous indignation with people pleading for Adele to think of the kids. Please.

And she admitted she's been given a talking to before the show.

"The BBC had to give me a warning about my potty mouth," she said. "Bet Muse didn't get that!"

Not that it helped.

Oh, and she also accidentally burped in the face of a young fan as they took a selfie on stage and blamed a "dirty burger". Nice.

The tents were flooded by toilet juice

It's fair to say that 2005 was not the time to be alive.

The rains fell hard. So hard that the toilets filled with water and overflowed, sending toxic rivers of fecal matter straight into the nearby tents.

Two months worth of rain pummeled down on the site in just a few hours as lightening struck.

The brave folk who dared pitch up next to the dance tent were hit the hardest by the toilet troubles, while others turned their air beds into dinghies and a good time was had by all.

Victoria Beckham made her debut - by helicopter

A muddy field is hardly VB's scene, but she made it her own by arriving in a private helicopter.

Determined not to lower herself to wellies, she wore skinny jeans, a printed blouse and a swish pair of ankle boots and quaffed red wine from a monogrammed flask as she watched Ed Sheeran with husband David.

While they looked loved-up in the pictures, sources claimed they had a backstage bust-up at around 7.30pm that had to be calmed by their son Brooklyn.

“Victoria wasn’t happy about being left alone in the VIP area. She was hanging around on her own for ages with minder types," the insider told The Sun.

“Then David came back and Victoria had a go at him and they were separated for a period. It was really awkward. Brooklyn came over to try and keep the peace.

“He said to David: ‘Don’t worry dad I’ll get you a drink.’ He then ordered him a double gin and tonic.”

A source close to the couple insisted it was "over in seconds" and that they went on to have a "great night".

The BBC's attempt to subtitle Kayne West ends gloriously

The Beeb did it's best to keep on top of the lyrics to Kanye's All Day and make them as PG as possible.

Alterations such as "ligger motherducker" had viewers at home in stitches before the channel ran out of ideas and simply wrote, "He raps".

Genius.
