Pink Floyd has to be one of the most successful rock bands of all time - selling more than 250 million records.
And Nick Mason was the drummer and a founding member - he's also the only member to feature on all the band's albums.
Back in 2018 - Mason formed the band, Saucerful of Secrets, and they've been performing early Pink Floyd songs to rave reviews.
And now they have a live album from their 2019 performance at London's legendary roundhouse that is titled Live at the Roundhouse.
Nick Mason joined Mike Hosking for a chat.
