background throughout the song. When Berry Gordy heard the completed song, he decided to release it as the final Diana Ross & the Supremes song. Neither of the Supremes' remaining members, however, sang on the record. Ross's first solo single instead, released in early 1970, became "Reach Out and Touch (Somebody's Hand)". Even though the implicit subject of the song was that of Ross comforting a long-distance lover, "Someday We'll Be Together" allowed for other interpretations, one being that Ross and bandmates Mary Wilson and Cindy Birdsong would one day nostalgically "be together" again. Further, in concert, Ross would suggest that "someday, we'll be together" in regard to contemporary troubles like civil rights and the ongoing demonstrations and protests against the Vietnam War. Release "Someday We'll Be Together" was included on the final Diana Ross & the Supremes album, Cream of the Crop (1969). The song was a United States number-one hit on both the Billboard Hot 100 popular singles chart and the R&B singles charts, as well as charting in the top twenty at number 13 on the UK Singles Chart. It also peaked on the Netherlands' MegaCharts at #19 in 1970. "Someday's" B-side, "He's My Sunny Boy", was recorded by Ross, Wilson, and Birdsong for the Love Child album in 1968 and written and produced by Smokey Robinson. "Someday" charted at number-one on the Billboard Hot 100 popular singles chart for one week, on December 27, 1969. It also charted at number-one on the Billboard R&B Singles chart for four weeks, from December 13, 1969, to January 3, 1970. "Someday We'll Be Together" therefore appeared in Billboard as both the final Hot 100 and R&B number-one of the 1960s, and as the first R&B number-one of the 1970s. Notable live performances The girl group made their final of several performances throughout the decade 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
