 Produced under a Memphis soul sound similar to soul singer Aretha Franklin, the song has the narrator (lead singer Martha Reeves) promising to wait for her love as he fights in Vietnam, although the song does not overtly reference the war, disguising it as the war being another woman saying that she will love him "even though (he does her) wrong".

 This time, lead singer Martha Reeves explains how her loved one brings her "closer" to him explaining that his love was like "quicksand".
 Released in November 1963 on the Gordy label, the song became another Top Ten hit for Martha & the Vandellas, eventually reaching number eight on the "Billboard" Hot 100.
 It was the third hit on which the group collaborated with the famed Holland–Dozier–Holland team, who would go on to record hits with the likes of Vandellas' contemporaries, The Supremes and the Four Tops.
