 While traveling as part of Motown's Motortown Revue later that year, Robinson and fellow Miracles member Ronnie White wrote "My Girl", which the Temptations recorded in the fall of 1964 with Ruffin singing his first lead vocal for the group.Released as a single on December 21, 1964, the song became the Temptations' first number-one pop hit in March 1965.Over 50 years and multiple chart topping songs later, it is still their signature song to this day.
