Ezrin's suggestion to release "Another Brick in the Wall, Part 2" as a single with a disco-style beat did not initially find favour with Gilmour, although Mason and Waters were more enthusiastic. Waters opposed releasing a single, but became receptive once he listened to Ezrin and Guthrie's mix. With two identical verses the song was felt to be lacking, and so a copy was sent to Griffiths in London with a request to find children to perform several versions of the lyrics. Griffiths contacted Alun Renshaw, head of music at the nearby Islington Green school, who was enthusiastic, saying: "I wanted to make music relevant to the kids – not just sitting around listening to Tchaikovsky. I thought the lyrics were great – 'We don't need no education, we don't need no thought control ...' I just thought it would be a wonderful experience for the kids."
