‘Ed Sheeran asked us for work experience then drank all our beer’: Nizlopi on making JCB Song

‘We’d get big, rugby-playing men coming up to us in tears and saying “I miss my dad” – or “I love my dad and I’ve never told him”’

John and I started writing songs together when we were 13. After we finished at university, we both moved back in with our parents in the Midlands and started writing an album. One day I went downstairs and my dad was cooking. I said: “What should I write a song about?” And he was like: “I don’t know. Diggers.” He drove a Massey Ferguson digger in his own father’s groundworks company and would pick me up from school in it straight from a job. One kid a couple of years older than me at school would often pummel me, and my dad always felt so warm, loving and safe by contrast. The two worlds were a massive juxtaposition. I went upstairs and 90 minutes later more or less had the song exactly as it was recorded.
