Pink Floyd's Roger Waters has said he would consider performing on the border between the US and Mexico as an act of "celebration" against the rhetoric of building walls.
The veteran musician, who lives in the US, hit out at President Donald Trump's plans to construct a permanent security barrier along the border, although he also said he does not believe the controversial Republican will survive four years as leader.
The 73-year-old famously commemorated the fall of the Berlin Wall with a live performance in 1990 to an estimated near half a million crowd in the German city.
It followed Pink Floyd's own The Wall tour from their album of the same name in 1980, while Waters later took his own version of the show on a world tour.
Speaking alongside the band's drummer Nick Mason at a preview of the upcoming Pink Floyd retrospective exhibition at the V&A in London, Waters said Mr Trump will face mass protests when he visits the UK.
Waters said: "I get asked quite often if I'd do The Wall again because I stopped a couple of years ago.
"I've always said I'd do it again if they ever figure out what to do about Israel and Palestine and get rid of that appalling security barrier.
"If there was a resolution and we could realise there is no 'us and them' and that we're all human beings and we all need to figure out how to live together because at the moment... as an act of celebration, if that moved towards a humane way of organising ourselves, I would be only too happy to perform that concert in some place that was significant geographically.
"If that happened to be the border between the United States and Mexico then yeah absolutely.
"But there needs to be an awakening period... before something like that can happen.
"Trump and Theresa May and the right wing as you know is raising its ugly head all around the world so yeah as an act of celebration it would be.
"The sewers are clogging with greedy powerful men as we speak and they are backing up and that is what is causing this stuff."
He later told the Press Association he doubts Mr Trump will last four years, adding: "The trouble is if he stops being president you'll then have President Pence, and this is a man who a couple of weeks ago I believe, declared the bible should be taught as science in schools.
"It's very strange the way things have swung into the realm of the absurd in the United States of America."
On the prospect of the US leader travelling to the UK for a visit, Waters said: "I'm quite sure if President Trump comes to this country there will be an enormous taking to the streets.
"I think we would see demonstrations in London bigger than any demonstrations than have ever been seen."
Earlier this week th e Foreign Office rejected a 1.85 million-strong petition calling for Mr Trump's trip to be downgraded, stripping it of the trappings of a full state visit.
The pair also revealed they would consider playing Glastonbury, with Mason saying: "I think it would be nice to add it to the list. It would be fun to do it, but I don't think its very likely."
Waters said: "I did Glastonbury once. It was really cold ... there were a lot of people and it seemed very jolly. I'd do it again."
