Speaking about how their collab came about, Noah Kahan explained: “When I first heard Sam Fender’s music, I stopped what I was doing, started [playing] ‘Dead Boys’ from the beginning, and listened four more times. It was everything I loved about a song.
“I followed this artist like a crazy person, checking every day to see if he had dropped new music. Reading every lyric and looking for his interpretation of what they meant. I must have listened to ‘Hypersonic Missiles’ 1,000 times before ‘Seventeen Going Under’ came out, and I had never felt so connected to a song.
