"We Can Always Come Back To This" was written by This Is Us
composer Siddhartha Khosla and the singer-songwriter Chris Pierce. They met 10 years earlier at the South by Southwest festival, where Khosla was performing with his band Gold Spot. Khosla had a tough assignment: write a soul song that sounds like it could have been a hit around 1970, and reflects the feelings of a character dealing with the loss of a loved one. Khosla thought of Pierce, and rang him up for assistance. They got together and wrote the song, with Pierce drawing on personal experience. On the Songfacts Podcast, he explained
: "It immediately resonated with me as I had lost my dad a few years before and he was really into soul. When I saw the picture of the scene, it immediately reminded me of my dad, and I really drew from my own experience of loss while writing it. Within an hour we submitted it to the executive producers and they loved it."
