 From "Reflections" in 1967 to "The Weight" in 1969, only six out of the eleven released singles reached the Top 20, and only one of those, 1968's "Love Child", made it to number one.Due to the tension within the group and stringent touring schedules, neither Mary Wilson nor Cindy Birdsong appear on many of these singles; they were replaced on these recordings by session singers such as the Andantes.The changes within the group and their decreasing sales were signs of changes within the music industry.
