The trek was slated to begin in New Orleans, Louisiana on May 15, 2020, but the two singer/songwriters have decided to shelve the dates and plan a road trip later in the year.
A statement from the duo reads, "As this summer's tour of 27 towns and cities across the U.S. drew near, we've been increasingly excited to hit the road again, so it's deeply disappointing for both of us to have to call it off and reschedule (and reschedule we WILL)!"
"As we all now realize, COVID-19 is a serious, real and present danger. Moreover, our public health is all of our responsibility. So let us listen to and follow the directions of our public healthcare people and support their efforts in this unprecedented time of global pandemic. Love those around you and, above all, stay safe and healthy."
Browne recently tested positive for COVID-19, telling Rolling Stone he has mild symptoms and is spending time in quarantine at his home in Los Angeles.
Meanwhile, Niall Horan has been forced to cancel his upcoming "Nice to Meet Ya World Tour" due to the pandemic, also announcing the news to fans on social media on Friday, April 3, 2020.
"Given the unprecedented circumstances I have decided to not move forward with the 'Nice To Meet Ya' world tour this year," he writes. "This was a difficult decision, but the well-being of my fans and touring family is always my top priority."
"Not being able to tour for what is effectively most of 2020 just didn't feel right and I'm so sorry to all you amazing people who bought tickets. I look forward to being able to bring new music and a new tour for all of my fans around the world in 2021. I want to announce new dates soon but I don't think it's fair on you guys to do so until the dust has settled and things have gone back to normal."
"For the time being, please stay safe everyone. Love you all."
The pandemic has forced the cancellation or postponement of a series of top tours headlined by the likes of Green Day, Foo Fighters, BTS (Bangtan Boys), Slipknot, and the Zac Brown Band, as well as all major music festivals and events around the world.
