The title track of the Doobie Brothers’ brand new studio album, Walk This Road, is a thinly condemnation of the Donald Trump-led administration. In a brand new interview in the current issue of Classic Rock, McDonald – who co-wrote the song with Doobies producer John Shanks – reveals that the track was inspired by his worries that the nation could be heading towards “totalitarianism” at the hands of Trump and associates.

“I think it’s important that all of us stand up and say our piece,” McDonald says of the track, which features an appearance from legendary US singer Mavis Staples. “Here in the US these are perilous times, I’m afraid. We are staring down a dark channel that could lead to totalitarianism.

“We’ve got a guy who doesn’t want to be President Of The Unites States as much as he wants to be one of the points of light – the whole axis of everything. He wants the world.

“We have to be very careful of that, and we should speak out against it while we still can. I have no doubt that should they get their own way, this administration would shut down the press completely.”
