Someday We'll Be Together with Diana Ross singing lead on the 1960s decennial finale of "The Ed Sullivan Show" that aired live Sunday, December 21, 1969 on CBS. "Someday We'll Be Together" was the final number at Diana Ross & the Supremes' farewell concert on January 14, 1970 at the Frontier Hotel in Las Vegas. After the completion of the show, Jean Terrell was presented onstage to the audience as Diana Ross' replacement (alongside Wilson and Birdsong). Thus "Diana Ross & the Supremes" officially split apart, becoming "Diana Ross" (the solo act) and "The Supremes" (the group). Ross reunited with Wilson and Birdsong in
Missing You (Diana Ross song) Love" album. The music video, directed by Dominic Orlando, was filmed on location at Caesars Palace on the Las Vegas Strip in Las Vegas, Nevada. The video includes, in addition to still photographs and tribute clips of Gaye, tribute clips of the former Supremes singer Florence Ballard and of Paul Williams of The Temptations, both Motown artists who had died in the 1970s. The song was built during conversations about Gaye shared by Ross and Richie, who came up with a song shortly after the conversations. Released in late 1984, the song became Diana's last major hit on the U.S.
