Pink Floyd’s living co-founders, Roger Waters and Nick Mason, got together for a reunion to celebrate the band’s 50th anniversary.

Together, two of the prog rock band’s surviving members helped to unveil an honorary plaque at the University of Westminster in London, according to Rolling Stone. The school used to be called Regent Street Polytechnic, and was the place where Pink Floyd was formed. In talking about those days, Mason said, “Put it like this: if we’d gone up for Britain’s Got Talent, I don’t think we would have made it past the audition stage; we weren’t terribly good,” while Waters referred to early Pink Floyd as “effing awful.” Below is a brief video of the unveiling and an interview with Mason and Waters afterward.

It’s true that Pink Floyd has a rocky history, including a lawsuit filed by Waters against Mason and David Gilmour, who couldn’t make it to the event. Waters later admitted he regrets the lawsuit. The two musicians were getting along well at the event, but in a recent interview with the Times UK, Waters said, “A reunion is out of the question. Life, after all, gets shorter and shorter the closer you get to the end of it and time becomes more and more precious and in my view should be entirely devoted to doing the things you want to do. One can’t always look backwards.”

Waters’ philosophy matches up with Gilmour’s 2014 statement that The Endless River, the group’s first album since 1994’s The Division Bell, may be their last.
