On this day in music history: October 26, 1974 – “Then Came You” by The Spinners and Dionne Warwick hits #1 on the Billboard Hot 100 for one week also peaking at #2 on the R&B singles chart on October 19, 1974. Written by Sherman Marshall and Phil Pugh, it is the lone pop chart topper for the Detroit based vocal group and the first for the Pop/R&B vocalist. Producer Thom Bell will suggest the duet after The Spinners and Warwick appear on the same live concert bill in Las Vegas. After they record “Then Came You”, Warwick believing the song won’t be a hit, makes a bet with Bell. They take a dollar bill and tear it in half, each taking half. The loser of the bet has to send their half of the dollar to the winner. Released as a stand alone single on July 13, 1974 (later included on The Spinners’ album “New And Improved” and Warwick’s “Then Came You”), it quickly becomes a smash. Entering the Hot 100 #51 on July 27, 1974, it climbs to the top of the chart thirteen weeks later. The single quickly sells over a million copies and earn them a Grammy nomination for Best R&B Vocal Performance By A Duo Or Group. Warwick sends Bell her half of the dollar back along with an apology for being wrong about the songs’ hit potential. The song also makes Billboard chart history when it takes the biggest fall from top spot, dropping to #15 the week of November 2, 1974, tieing with Billy Preston’s “Nothing From Nothing” which it had replaced at number one and took the same downward trajectory. “Then Came You” is certified Gold in the US by the RIAA.
