The Supremes were determined to promote their new line-up, with the loss of the biggest star.
The trio gave viewers a special mini-concert on the night, performing Brothers Love Traveling Salvation Show, Loves Country, Together We Can Make Such Sweet Music, and Steeling In The Name Of Good Lord.
But the highlight was an electrifying rendition of the Ike and Tina Tuner classic River Deep, Mountain High.
Midway through the song, Tom sauntered on and took up the second verse.
Many of those watching at the time would have known or at least suspected that he was singing next to the woman he had a prolonged affair with.
Linda had always avoided the limelight, while Tom was frequently seen with a parade of beautiful women.
