Sir Bob Geldof has launched a blistering attack on Elon Musk labelling him a ‘w***er’ and a ‘ketamine-crazed fool’.

The Boomtown Rats frontman made the remarks at the opening night of Just For One Day: The Live Aid Musical at the Shaftesbury theatre in London’s West End.

The 73-year-old rocker took particular exception to Elon’s cuts to the US aid budget during his time at the White House heading the Department of Government Efficiency.

He also criticised the Tesla boss for his recent remarks when Musk said: ‘The fundamental weakness of Western civilization is empathy, the empathy exploit.’

Firing back Bob took aim at Elon, he said: ‘A couple of weeks ago, that prime wanker Elon Musk said something seriously wrong. He said the great weakness of Western civilisation is empathy.’

‘The great weakness? You ketamine-crazed fool! You sociopathic loser! Empathy is the glue of civilisation. Empathy is the glue of humanity.’

‘It’s how we do things together. It’s how we sit here together and clap because we actually understand that this is the stuff that works.

The musical, which has finished a run in Toronto, Canada last year, gives 10 per cent of its ticket revenues to the Band Aid charity and has already raised almost £1 million.

Bob said: ‘The money these people have raised has already – in the place that was the epicentre of the famine in 1984 – they’ve already built hospitals and schools and stuff like that with the money by doing their job tonight. That’s what they’ve achieved.’

The musician then turned his sights on President Trump for his decision to remove funding for USAid on February 1, and Prime Minister Starmer for cuts to overseas aid spending.

Bob said: ‘On the February 1 this year, the strongest nation in the world, the most powerful man on Earth, and the richest person ever in the history of the planet decided to declare war on the poorest, the weakest, and the most vulnerable people on the planet. I despise them.’

‘The net result of that is that Boston University, and reported in the New York Times, is that since February, because they cut out overnight when US Aid websites went dark and fired everyone.

‘Since that day a couple of months ago, 300,000 people have died because of Musk, because of Trump, because of Vance. and Marco Rubio is lying when they say people have not died.

‘When they say they are sending food to the starving children of Sudan, who are being held captive and starved to death.

‘That’s a lie. They are not. So it’s down to us to scrape together a million quid.

The Irishman said it was a ‘great shame’ that Keir Starmer had cut aid budgets.

He added: ‘It can’t work like that. It doesn’t have to work like that. And it began not working like that in 1985.

‘This is Great Britain. This country can do anything. It led the way for many years, and times are really tough. Believe me. Times are really hard, but we don’t let ourselves go. And these people aren’t, and you didn’t tonight.’

In the new musical Sir Bob is played by Craige Els, who the rock star described as ‘amazing’ for the portrayal of him as a ‘cartoon arsehole in double denim just saying “f***”, basically’.

Live Aid, was originally held in Philadelphia as well as at Wembley Stadium on 13 July 1985, and has been turned into a stage musical.

Titled Just For One Day, the musical relives the day when the likes of Bob Dylan, David Bowie, The Who, U2, Queen, Elton John, Paul McCartney, Diana Ross and more united on stage to raise funds and awareness for the Ethiopian famine crisis.

The plot of the production, which takes its name from a line in David Bowie’s song Heroes, combines a behind-the-scenes look at how Band Aid and Live Aid came together with a love story inspired by real events.
