Simon involved guest musicians, including American singer Linda Ronstadt and his childhood heroes the Everly Brothers. During a trip to Louisiana with Richard Landry, he saw a performance by the Layafette zydeco band Good Rockin' Dopsie and the Twisters, and recorded "That Was Your Mother" with them in a small studio behind a music store. He felt that the accordion, central to zydeco, would make a pleasing transition back to his own culture. Afterward, he contacted Mexican-American band Los Lobos, with which he recorded "All Around the World or The Myth of Fingerprints" in Los Angeles.
