According to Tony Turner, author of "All That Glittered," The Supremes were rehearsing for their Copa debut. Florence Ballard started singing "People." It sounded fabulous. She was tearing the song up, inside and out, it sounded nothing like the Streisand version. Everybody was listening until Harvey Fuqua said, "There's going to be a change in the show." 'People,' will not be in the performance.
Flo exploded, saying, "She (Diana Ross) will never get away with it." Flo storms out, she's ranting and raving down the sidewalk, 'Flo's not taking this shit.' When we get back to the Plaza, Flo held her door wide open with a chair. She looked at me and said, "Tony, it's like a game of concentration. When you get a take card you get to take your opponent's prize. Berry Gordy is Diana's take card. Diana never cared about Berry until she knew I was interested in him. He and I used to get along just great until that b**ch came along."
Get Mary on the phone! She stayed there with the door open, she complained to everyone coming back from rehearsal. Mary arrived, she just sat there, not saying anything, as Flo went on and on. Diana and Berry had the sense not to go near Flo's suite that night.
Flo continued cursing and said, "I'll bet you that Diana Ross is going to be up on that Copa stage singing my goddam song!" Sure enough, after a few days, "People" was put back into the show and now it was Diana up on the stage singing the song."
After the show, Flo was in the dressing room, she started to belt out "People," nobody in the dressing room said a word. Flo did the whole song in a cappella. She held the last note for five minutes, outside the dressing room, people began clapping and stomping their feet.
