With Alomar gone, Rodgers took his place on rhythm guitar. He also recruited the majority of the new personnel, which included his regular Chic collaborators, keyboardist Robert Sabino and percussionist Sammy Figueroa, along with backing vocalists Frank and George Simms. The remaining musicians included drummer Omar Hakim (whom Bowie called "a fascinating drummer with impeccable timing"), bassist Carmine Rojas, trumpeter Mac Gollehon, and the saxophonists Stan Harrison, Robert Aaron and Steve Elson. Near the end of the sessions, Rodgers hired Chic drummer Tony Thompson and bassist Bernard Edwards for additional work; he failed to hire them initially due to the two's past drug use. Due to their arrival time, Thompson and Edwards' contributions were limiting, appearing on only three tracks and one track, "Without You", respectively. Edwards recorded his part for "Without You" in 13 minutes, with Rodgers later writing in his memoir, "I was never more proud of him in my life and it happened on the last day of basic recording." For the first time ever, Bowie himself played no instruments on the album. "I don't play a damned thing. This was a singer's album," he said. Bowie recorded all of his vocals for the album in two days.
