The January 1985 recording session was held during and after the American Music Awards at the A&M Studios in Hollywood, California. Michael Jackson skipped the American Music Awards ceremony, that night, to record the chorus of the song as a guide to the other artists. The artists who performed on "We Are the World" arrived in-studio from limousines (as most of them had participated in the awards show previously) - except Bruce Springsteen, who arrived driving a pickup truck. Prince's agreement to attend had been tentative, and he did not appear. Prince's absence was parodied in a Saturday Night Live sketch that referenced the actual arrest of his bodyguards who were involved in a scuffle the evening of the American Music Awards.

Many of the male singers found in rehearsal that the key of the chorus was too high for them to reach, so Quincy Jones told them to refrain from singing until later in the session when the chorus was switched to a lower key. For purposes of the video recording, some of the singers proceeded to pretend to sing.[2] Four of the men, Waylon Jennings, Kenny Rogers, Bruce Springsteen and Willie Nelson, stepped to the side during this time until the key could be recalibrated.

Bob Dylan was unaccustomed to delivering lines while surrounded by so many people in the studio. Stevie Wonder demonstrated the lines while mirroring Dylan's voice at the piano, and when Dylan delivered his solo perfectly, the room burst into applause.

Cyndi Lauper's jewelry clicking required a retake of the bridge section and during a break in the session, Al Jarreau and Lionel Richie broke into an impromptu version of Harry Belafonte's 1950s hit "Banana Boat Song (Day-O)" in honor of Belafonte's role in organizing the project which led to a suggestion, "This should be the B-Side." Wonder added a chorus to "Day-O" about his and Ray Charles' blindness. Wonder came back after the session to "touch up" his vocals.
