The first night of recording, January 22, 1985, had tight security on hand, as Richie, Jackson, Wonder, and Jones started work on "We Are the World" at Kenny Rogers' Lion Share Recording Studio. The studio, on Beverly Boulevard in Los Angeles, was filled with session musicians, technicians, video crews, retinue, assistants, and organizers as the celebrity musicians entered. Jones hired session musicians to lay down the backing tracks: John "JR" Robinson on drums, Louis Johnson on bass, and pianist Greg Phillinganes. (These three first played together on "Don't Stop 'Til You Get Enough" produced by Jones for Jackson.) Richie sat down at the piano to teach everyone the song. When it was time to roll tape, Robinson cleared the room of non-musicians, and the backing tracks were recorded. After this, a vocal guide of "We Are the World" was recorded by Richie and Jackson, mixed with the instrumental tracks, and duplicated on tape for each of the invited performers. The guide was recorded on the sixth take, as Jones felt that there was too much "thought" in the previous versions.
