The song finds Turner searching four different pubs for his ex but in each one he only finds her doppelgangers. The first three verses end badly when he asks the lookalikes, "Can I call you her name?" Turner told Vulture
the story behind the track:
"I was listening to a lot of country music when I wrote it, and it had that formula where the verses always end the same way. That happens a lot in Patsy Cline tunes. I started with the line 'I smelt your scent on the seat belt.' In reality, I was sitting in the back of a taxi and I got this scent in my nostrils of whomever I was longing for. I may have also had the names of the pubs in mind."
The ballad's last verse finds Turner meeting his ex's sister in the titular Cornerstone pub. "I'm not sure how I ended up with the girl's sister in the last verse," he admitted. "When I was in school, I think I probably fancied my girlfriend's sister or something."
