Bruce Springsteen has reignited his long-running feud with Donald Trump

Speaking to The Sunday Times, he said about Trump's reign in the White House and the current political climate in the States: "It's an American tragedy."

Trump, 79, has responded to Bruce's previous criticisms from Bruce by branding the singer a "dried out prune" who "ought to keep his mouth shut until he gets back in the country".

Clearly unmoved by Trump's comments, Bruce continued his criticism in his Sunday Times interview, saying: "We're living through a terrible moment in history, where Congress has neutered itself and the boundaries that once curtailed this type of leadership have disintegrated."

He added: "The pure incompetence of (the administration) may carry the seeds of its own destruction. But I don't know what's going to happen. I haven't lived through a time like this in my entire life and I'm 75 years old."

Speaking on the topic of fame and his decision to return to his home state of New Jersey, Bruce explained how staying connected to his roots has helped him remain grounded.

He said: "I don't believe we lose any part of ourselves. The first 20 years shape you, maybe longer in my case because I signed a lot of bad deals and at 30 I still only had $20,000 in the bank. I remain curious about the world.

"And coming back to New Jersey is the best decision I ever made, because it means I'm in the community. I know the mayor, the priest, the barber. I'm friends with the guys I was in bands with at 15, and we'll meet down at the pizza parlour once a year. Maintaining those connections is a joyful part of my life."

Reflecting on his decades-long music career, Bruce also said he's learned from those who came before him. "Of course, and I was lucky enough to have Elvis, The Beatles and Bob Dylan, to follow in their footsteps - or not follow in their footsteps," he said. "From there I learnt how important it was not to lose focus on who I am or the work I'm doing.

"It's more important than the money, although it's great to get paid well. It's more important than the fame, although that can be fun too, and a nuisance on occasion."

He added: "I simply wanted to write great songs, play great shows and have a conversation with a great audience. It is what I've dedicated my life to doing."
