Hundreds of fans walked out of the Brentwood Festival in Essex after singer-songwriter Bob Geldof, who was making an appearance with his band The Boomtown Rats, launched an expletive-laden rant at the crowd.

The Daily Mail reports that the 64-year-old began shouting as soon as he took to the state and stopped his performance after just one song, calling the family-friendly event “boring and tame.”

“We don't do Abba. We don't do Robbie f****** Williams. Brentwood, we are the Boomtown Rats,” Geldof shouted at the crowd.

“We are mega. And you are Brentwood. How do we know that you are Brentwood and we are mega?

“Because I am wearing a f*** off pretend snakeskin suit and [they] are wearing f*** off cowboy shirts even though they live in London,” said Geldof, who was wearing a £350 snakeskin suit he had made for him by a tailor on London's Brick Lane.

Referring to a member of his band, he said: “This [guy] who you'll remember as a slim handsome young lad is wearing a f*** off purple suit with an elasticated waistband so that when he gets even f****** fatter you won't notice.”

He then insulted the crowd by accusing them of not dressing edgy enough for a music festival.

“On the other hand Brentwood, you are wearing wall to wall f*****g Primark,” he said.

“This is a rock and roll festival. When you come to a rock and roll festival you dress for a rock and roll festival. You can never be too careful. 

“That song we just did was written at the end of 1975 when Margaret Thatcher became leader of the opposition.” 
When the crowd began to boo at him, he responded: “What are you booing for? We're in f****** Brexit land here guys. Yeah, we're Irish, we're still in Europe.

“It's just as well we wrote that song because this year is about Theresa May. She's gonna do you in.

“There's always someone looking at you Brentwood.”

During a performance of ‘I Don't Like Mondays,’ he paused and stayed silent for 90 seconds.

Fans took to Twitter to vent their frustration at Geldof’s outburst.

Lydz Oldershaw said: "Bob Geldof swearing and going mental at Brentwood festival was so inappropriate *telling the crowd off for wearing Primark*."

Another Twitter user, @ballsandbeers, said: "Horrendous individual, who loves the sound of his own voice. He hasn't made a decent track in decades."

Said one festival-goer, who left with her husband before the end of the concert: “They sounded pretty dreadful, especially after just hearing the fantastic voice of Tony Hadley, and of course they have a very limited back catalogue.

“We were just thinking we probably wouldn't bother staying to hear I Don't Like Mondays as it didn't look like it would be worth the wait when Bob launched into an extraordinary, expletive-laden rant.

“As he launched into another dreadful song, we, along with hoards of others, headed for the exit and I found myself in a queue to leave in the middle of the headline set.”

“All around you could hear mutterings from fed up festival-goers of how disgusting he was and 'how dare he'.

“It was a shame he had marred what was otherwise a fabulous day out.”

Laurie Edmonds, the festival coordinator, apologized for the language, but said it was all “part of the act.”

“They're a punk band. You expect them to be a bit controversial and he got a reaction from the crowd.

“People know he speaks his mind. That's just what they do but they were a fantastic punk band and we thought it would go down well with our crowds.

“We know he's a bit of a lightning rod and people will have strong reactions to him.

“We were disappointed that there was so much swearing. We want this to be a family event and it would have been nice if it was toned down.

“Some people who felt it was offensive made the decision to leave.

“We're truly sorry if people were offended. It wasn't our intention in booking them.

“We have had a couple of complaints but we've equally had people saying they were one of the best sets all weekend.

“There were still several thousands of people who stayed to the very end and were asking for encores.”
