One of the most legendary Motown tracks. The "No hit" Supremes scored their first #1, in August 1964. Their success was such that also the next four singles went to #1 and the trio became the most succesful girl group ever. Diana Ross, Mary Wilson and Florence Ballard apparently weren't so keen on the song first but after string of non succesful singles they didn't really have a say and went on to record it. Mike Valvano stomped his feet at the studio floor and the rest is history, as they say.
Just like with My guy/My girl, also this song got a brotherly version when Four Tops released I can't help myself (Sugar pie honey bunch), another #1 hit for Motown in 1965.
The melody line is almost identical.
