In 1965, Roger Water, Richard Wright, and Nick Mason were just students at the Regent Street Polytechnic school. Of course, they went on to form Pink Floyd, one of the most influential bands of the 20th century.

The anniversary of Floyd’s formation did not go unnoticed, as the band was commemorated with Regent Street Heritage Plaque. They’re just the second music act to receive such an honor; the first is on London’s Heddon Street, where the cover of David Bowie’s The Rise and Fall of Ziggy Stardust and the Spiders From Mars was taken.

Waters and Mason were both on hand for the plaque unveiling ceremony, despite recent tensions when Mason & Gilmour released The Endless River last year. Gilmour didn’t join the band until 1967, which is why he wasn’t present.

The two reminisced about the early days of Pink Floyd, with Mason saying, “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.” Waters added, “We were effing awful.”
