Sir Bob Geldof took to the high seas to oppose U.K. politician Nigel Farage over the European referendum.
In bizarre scenes the two camps clashed on the River Thames in London while on board opposing boats.
The Live Aid supremo boarded a boat to oppose UKIP politician (United Kingdom Independence Party) Farage's 35-strong pro-Brexit flotilla, which was making its way up the Thames towards parliament. Brexit is an abbreviation of "British exit" that mirrors the term Grexit (Greek Exit). It refers to the possibility that Britain will withdraw from the European Union. The country will hold an in-out referendum on its EU membership on 23 June 16.
The flotilla had been organised by Scottish skippers as part of the Fishing for Leave campaign. The Boomtown Rats frontman and Farage are at odds over the impact leaving the EU would have on the British fishing industry.
Although there was a larger contingent of Brexit boats, Sir Bob had armed himself with a huge sound system to try and drown out the flotilla, and later was joined by a few smaller boats who offered support.
The singing star blasted out songs including Chicago's If You Leave Me Now and Dobie Gray's The 'In' Crowd.
But the Leave boats retaliated to Geldof's musical warfare by firing water from a hose at his boat.
British newspaper The Evening Standard reports Geldof told Farage, addressing him over a PA system on his vessel, the Sarpedon: "You are no fisherman's friend.
"You are a fraud, Nigel. Go back down the river because you are up one without a canoe or a paddle."
The political rivals are attempting to galvanise support in the closing days of the EU referendum campaign. Later Farage told reporters the Geldof protest was "just disgusting".
